Fix condor configuration by options

Create run, spool, and log directories for the condor client. Reflect
configuration in condor config file template. Add option to set VMType
reported by condor client. Condor needs to be resarted after changes by
puppet.  Make CONDOR_CONFIG_VAL dependent on osfamily and set value
accordingly in the condor init script. Add condor startup functionality
to interact properly with GCE metadata.
