Change underlying SSH library #57

Open ahitrin opened 9 years ago

Currently, SA code is bound to the deprecated version of MindTerm library. This library also has murky license policy. It's better to totally replace it with modern and free Java SSH library, like JSch or sshj.

Migration plan is available here.

Wrote initial plan here

More libraries (need verification/testing):

Apache SSHD - with small team, but evolving
SSHTool -- seems to be abandoned
Ganymed-SSH2 -- very little info found

Apache Mina could be used, at least, for testing purposes. It would be 100 times easier to migrate underlying SSH backend when having automated tests suite.

Hard to be done without #55. Prefer to implement/try #55 first

Well... current SSH implementation is way too old. It cannot even connect to new SSH servers:
