Title: Verify that sshpass is present for salt-ssh calls

Ref #7528

Salt ssh doesn't appear to tie into the logger at all, so I just used a
print for the error message. Wasn't sure if logging.getLogger was
correct in this instance.

I'm also flexible on which exception to raise -- SaltClientError seemed
like the most fitting.
