ssh support

[apinto]

This is actually some interesting feature, but needs to be done with very care because it can expose the whole server if a mistake is made.

But to answer joubertredrat question about "why not?" I can tell almost for sure that this is not essential, can create other critical issues and will steer the dev team from the main objective of sentora.

I vote for this, but as a module, not on core sentora.
