Red Hat Satellite bootstrap.py failing for activation-keys or org-labels with spaces.

Issue

If the bootstrap.py script is used with -o (--organization) or -a (--activationkey) options, and the arguments to those options contain whitespace in either the name of the organization or the activation key, then a call to the /usr/sbin/rhn-migrate-classic-to-rhsm script will fail during execution with an error similar to this...

# /root/bootstrap.py --force -l admin -s satellite6.example.com -o 'myorg' -L 'mylocation' -g RHEL6_hostgroup -a "RHEL 6"
