Fixes ceph key import failures

There is an issue with HA deployments where sometimes key imports fail
for Ceph which seem to occur around 50% of the time.  When logging in
after a failure, the key import seems to work which indicates it may be
a race condition.  In addition, sometimes the keyring that is created
is missing the "caps" section of the file, which will also fail import.

This patch adds a retries for a minute to try to import the key.  It
also moves creating/importing to the same Exec because there is
evidence that the file is being modified by some other process right
after the file content is created in the previous exec.
