      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.

      A bunch of plab interface updates that I've worked on over the last while.
      Most significant is the revamped renewal code that tries to push the leases
      out to the policy defined maximum of two months during each iteration through
      the plabrenewd daemon loop.
      
      - added python lib code to get SiteVars
      - Fixed up comments to reflect current code operation
      - revamped renewal code (again)
        - changed all times to UTC for consistency
        - removed node-level renew invocation in favor of slice-level
          - if backend module requires node-level renewals, it must handle them
            itself in the slice-level function
          - better reporting
      - set admin bit if creating svc slice
        - other updates to ensure admin bit is preserved
      - update rootball handling function naming
      - updated tryXmlRpcCmd() to accept two new sets of strings, and a callback
        function.  The strings represent Faults that either 1) indicate success,
        or 2) indicate failure.  The callback is another optional error handling
        method, allowing the caller to decide how to treat individual faults as
        they see fit.
      - updated the backend module code to take advantage of the new string
        match status identifiers in tryXmlRpcCmd()
      - completely revamped slice renewal code in mod_PLC backend
        - compare against real lease expiration data gathered direct from PLC
        We used to just infer from our originally requested lease length
        - warn when our notion of expiration doesn't match PLC's
      - added agent caching and lease expiration info caching to mod_PLC
        backend.

      * Node.__copy() now uses rsync instead of weird 'dd' pipe
        - can do since sudo now works from square one after sliver instantiation
      
      * Made fixsudo and addgroup operations in emulabify() non-fatal
        - setup sometimes works even if they don't (esp. on dirty sliver)
      
      * option parser fixes
      
      * Shutup stupid warning messages from remote commands (tcgetattr, sudo lecture)

      * incompatible option handling and use removed from gen purpose libs
      * Global PLC mutex implemented, but currently disabled
      * plabmonitord parallelization cut in half (for now)
      
      I'm still very frustrated with option handling/passing.  Needs more thought,
      but the primary issue is that there really isn't a global variable space in
      python (global to file, yes, but not global to interpreter invocation).
      
      I've learned that __builtin__ might work for this, but it seems hacky..

      * Changed the way options are parsed in the python scripts so that modules
        can easily add and use their own options independent of top-level scripts.
      
      * Added --noIS and --pollNodes module options.
      
      * Added batch option to vnode_setup (degree of parallelization)
        - defaults to 10
      
      * Major updates to plamonitord
        - batches testing, currently to 40

      * implemented PLC slice renewal
      * restructured daemon code/startup
        - removed getfree daemon (replaced by plabdiscover; run from cron)
        - moved generic daemonizing code into libtestbed (class)
        - created plabrenewd - small script that utilizes daemonizing class
        - removed plabdaemon file.
        - updated bossnode startup scripts
      * changed slice prefix - PLC denies permission w/ anything other than "utah"
      * Minor semantic changes to module API to be more consistent with other parts.
      * Some bug fixes.

      Kirk takes the weed whacker to the plab code. This is the first pass result. · ae2eec76

      I'll come along for a closer cut in the future.
      
      * Modularized the plab communications 'adaptor' interface and moved the
        dslice- and PLC-specific code into their own modules.
      
      * Wrote an API definition README
      
      * Separated out generic routines from libplab into their own library modules
        (libtestbed.py and libdb.py)
      
      Functionally, not much has changed - this was just a massive re-org with some
      other cleanup.  Should be much easier to code up new PLAB interfaces as the
      plab folks flail around in their attempt to standardize on something.
      
      XXX: may want to re-think where the generic library modules should go.  If
      more python code enters Elab, we'll probably want to move 'em to more standard
      locations.
      
      This isn't the end of the cleanup - I would eventually like to go back and
      rethink the class structures, beef up the comments, and extend the API.
