known_hosts file recreated for each ssh connection.

You can help speeding up the fix by fixing it yourself by cutting a
internal release of wagon-ssh-beta-2+ and load it thru maven's
extensions to see if the problem goes away.

To make a quick fix, just comment out the place where knowhosts file
is rewritten

to fix this we need to do a comparison between the local copy and the one in sch instance

Attached is a patch where we check if an actual write is needed.

Even though the probability that the bug will happen is low, but it think it is worth the fix

I added a check please test out the deployed snapshot thru maven extensions tag
