testing: Reduce testing runtime by reusing SSH sessions.

By using the ControlMaster and ControlPath options, existing SSH sessions
are reused (a session to each host is opened at the beginning of a test
run).  Also, RC4 is used as encryption algorithm to further improve the
performance.  These changes reduce the runtime by over 20%.
