Redirect possible bash warning to null, it's harmless

From OSG Jira CAMPUS-89
Adding passwordless ssh-keygen to bosco_cluster add.

When bosco_cluster is run for the first time, it must create
an rsa key for passwordless ssh to the cluster.  We are able
to bypass the user supplying a password by generating one.

Fix bad file descriptor leak in the ft-gahp. #3559

A pipe was leaked on every UPLOAD_SANDBOX and DESTROY_SANDBOX command.
ft-gahp: return failure when creating child process fails. #3559

Otherwise, the gridmanager will wait for the command to finish.
Add support for RequestMemory to the blahp. #3398

Allow users of the blahp to specify the amount of memory required by the
job, using the same attribute as for HTCondor job ads. This number (in
megabytes) is passed to the submit scripts via the new -m parameter. The
PBS and Condor scripts now use it in the job submission. The other
submit scripts don't use it yet.
Update URLs in bosco_findplatform to bosco-1.2
