    Modernize elabinelab and Emulab install support a bit. · f7e53243

    Support FreeBSD 10.3. We will need to be moving to this before long
    as 10.2 EOLs in two days.
    
    Support setup of "Emulab-aware" ZFS use in install scripts. Note that
    the core support code was already done (WITHZFS, WITHAMD). Mostly this
    involves changes to setup either amd (WITHAMD==1) or autofs (WITHAMD==0)
    on the boss node and to NOT add mounts of /{users,groups,proj} to
    /etc/fstab. We still need to add a section to the install documentation
    about setting up a zpool for Emulab to use. There was also a fix to the
    firstuser script which did not do the account setup correctly.
    
    Support setup of ZFS in elabinelab. The elabinelab attributes CONFIG_ZFS
    and CONFIG_AUTOFS are used to convey intent here. Currently they can only
    be used in an "ops+fs" config (e.g., the standard boss and ops config,
    NOT the seperate fs node config). It should work with either the physical
    or virtual node setups:
    
    * For the physical node setup, we actually use local blockstores in the
      ops node config: a SYSVOL blockstore for /usr/testbed and a tiny 1Mib
      NONSYSVOL blockstore. The latter blockstore is not actually used, we
      just make it to force setup of a ZFS zpool which we then use for the
      inner elab.
    
    * For the virtual node setup, we just identify the virtual EXTRADISK
      intended for "/q" and create a zpool on that device.
    
    I would like to change all physical elabinelab setups to use blockstors
    rather than the current hacky mkextrafs usage. But that is a task for
    another day.
    
    Finally, a couple of random changes in elabinelab code: change the
    CentOS image downloaded to CENTOS7-64-STD, increased the default sizes
    of the EXTRADISKS used in the VM config.
