Utility to avoid gateway reconnections when using clush in scalable mode. This agent is optional.
The idea of '''clush-agent''' is that it is started in a login session on the management node so next clush instances are started as clients to the clush-agent program. Through use of environment variables, the agent can be located and automatically used to route clush requests.

This agent will be able to maintain one ssh connection to each selected gateway node, running there a clush in listen mode (clush -X).

'''Pros''': fastest execution (avoid ssh reconnection), still no daemon running on gateways!
'''Cons''': has to be fully secured within the login session
