1. MemoryError seen on expire_distros execution …

   When the beaker_expire_distros hourly cron job ran, the
   MemoryError is seen on the lab controller as well as Server.
   This same error is seen when executing the bkr CLI
   'bkr distro-trees-list --limit=8000 --labcontroller=hostname |
   grep "ID:" | wc -l'
   As it turns out, expire_distros is calling the same underlying
   get method.  The error is sporadic.  It is likely due to
   difficulty attaining a contiguous memory chunk for
   a lot of data.  The solution is to get smaller chunks.  Similar
   filters as the cli distro-trees-list are now allow thru
   expired_distros.py which passes them to the same get operation.
   These filters also allows for more variation for beaker_expire_distros.
   Stepping thru architectures seemed to be the best choice of filters
   for the chunks.  When --arch=all, the expire_distros.py code knows
   to step thru a list of arch to perform removal instead of trying
   to do it all at once. So the cron job is updated to include --arch=all.
