Add default_queue and default_maxMemory to the default route.

A system administrator can now use a condor config file to specify the
default queue and maxMemory a job should have when being submitted to
the LRMS.  The user's RSL will overwrite the admin supplied values.
Delete PeriodicRemove from the translated job.

A local PeriodicRemove can leak into the remote queues if they are not
deleted by the JobRouter.
