      tree for v4 planetlab node support.  Currently, we support both v3 and
      v4 NMs via a little wrapper, and we dist out different versions of the
      rootball depending on NM version.  Also updated various parts of libplab
      to log success and failure from interactions with planetlab nodes to the
      db, and there are beginnings of support for that in plabmonitord.in.

        * libplab.py.in:  add support for saving state at two PLCs, one primary,

        * mod_PLCNM.py.in: change URL to access old xmlrpc server since
            PlanetLab went ahead and changed DNS.

      plab logging enhancements.
      
      timing information for various RPCs is now logged to
      /usr/testbed/log/plabtiming.log.  This info will be useful for extracting
      trends for the various plab nodes, and in calculating reliability and
      timing metrics.  These could be used, for e.g., to pick nodes that tend to
      come up more quickly.
      
      This update also squelches much of the python backtrace noise when plab nodes
      fail to setup correctly (can be turned on with debug flag).  Instead, failures
      are summarized on a single line.
      
      Oh, and pay no attention to the aspect behind the curtain!  Yes, you may
      groan and moan if you wish - I'm using aspects to help do the logging.  I
      find this to be a really slick way of wrapping several functions!

      A node update bugfix and a change to the way nodes with more than two
      changed attributes are handled.  A single message is now sent detailing
      which nodes need to be looked at, and such nodes to not stop the rest from
      updating normally during that run.  Previously the nodes with multiple changes
      had to be handled first, then the update script had to be run after that to
      catch everything.

      A few little things:
      
      * Minor bugfix to node_type_attributes mod.
      * When we don't recognize the gateway, set type to "*Unknown*".  Should
        have always been doing this.
      * Add NLR gateway - new nodes detected here will be set to pcplabinet2,
        but this could easily be changed.

      Users that create Planetlab experiments will now get email coming back via
      the emulabman@emulab.net alias.  The technique is simple:  stash away the
      experiment head uid in a file corresponding to the slice's name over in
      ops:/etc/mail/plab-slice-addrs.  The silly procmail config file I've committed
      here reads this file (if it exists) and forwards mail to the user's email addr
      contained therein if the incoming message contains the name of their slice.
      There is no install target for this procmail filter;
      I hand installed it and hooked it in.

      Changes necessary for moving most of the stuff in the node_types · 624a0364
      Leigh B. Stoller authored
      table, into a new table called node_type_attributes, which is intended
      to be a more extensible way of describing nodes.
      
      The only things left in the node_types table will be type,class and the
      various isXXX boolean flags, since we use those in numerous joins all over
      the system (ie: when discriminating amongst nodes).
      
      For the most part, all of that other stuff is rarely used, or used in
      contexts where the information is needed, but not for type descrimination.
      Still, it made for a lot of queries to change!
      
      Along the way I added a NodeType library module that represents the type
      info as a perl object. I also beefed up the existing Node module, and
      started using it in more places. I also added an Interfaces module, but I
      have not done much with that yet.
      
      I have not yet removed all the slots from the node_types table; I plan to
      run the new code for a few days and then remove the slots.
      
      Example using the new NodeType object:
      
      	use NodeType;
      
      	my $typeinfo = NodeType->Lookup($type);
      
              if ($typeinfo->control_interface(\$control_iface) ||
                  !$control_iface) {
        	    warn "No control interface for $type is defined in the DB!\n";
              }
      
      or using the Node:
      
      	use Node;
      
              my $nodeobject = Node->Lookup($node_id);
              my $imageable  = $nodeobject->NodeTypeInfo()->imageable();
      or
              my $rebootable = $nodeobject->isrebootable();
      or
              $nodeobject->NodeTypeAttribute("control_interface", \$control_iface);
      
      Lots of way to accomplish the same thing, but the main point is that the
      Node is able to override the NodeType (if it wants to), which I think is
      necessary for flexibly describing one/two of a kind things like switches, etc.

      Fix up plab renewal for current scheme.  We must now go out to each sliver
      individually and ask for it to be renewed.  I've added a new script to be
      run out of cron that will run through and attempt to renew all active slices.
      If a node cannot be renewed with its slice and comes sufficiently close to
      it's recorded expiration (currently two weeks out), mail will be sent to
      testbed ops warning about this situation.  Note that there will only be
      one email message per slice, containing a list of all nodes at risk for
      expiration.  The plab renewal daemon will no longer run as a result of
      this change.  Note that this is sort of a hack.  The better way would be
      to have the daemon perisistenly try to renew nodes that have failed until
      success, but that will take more work, and I might farm it off to the
      plab monitoring daemon anyway.

      The revived Plab interface is here!
      
      Lots of updates to the plab backend, including improved plab <-> elab node
      id translation and update handling.  Includes support for the current PLC
      API, and the new pl_conf node manager interface API.  Several more db library
      routines were ported from the perl library to the python one to support the
      new code (mostly the node_id tracking stuff).  Fixes to the client side and
      also a rootball creation cleanup (binaries removed from the CVS repo).
      
      There are also enhancements to the experiment view page for experiments
      including plab nodes: site and widearea hostname are now displayed along
      with the other node information.
      
      Note that the way setup timeout for vnodes is calculated has been changed a
      bit.  Instead of using a hardwired base timeout, the base timeout is now
      based on the reload_waittime database field, which comes from the 'OS'
      (e.g., FBSD-JAIL, RHL-PLAB) the vnode runs.
      
      The default max duration for a plab slice created through the plab_ez interface
      is set to 1 year, and linktest is currently disabled and hidden through
      the ez interface.
      
      There is still work to do, but this checkin brings with it a functional
      plab portal!

      * the python mysql client returns a datetime object rather than a string

      * PLAB changed format of expiration time in listSlices() RPC from a
        datetime string to seconds since the epoch in UTC.
      
      There is still an outstanding issue that I have mailed plab support about:
      The listSlices() RPC is only returning the first entry in the list of slices
      we have allocated at PLC (the same call used to grab all slice entries).
      This is causing us to fail on renewal for the unlisted slices.
