ssh: log the libssh2 error message when ssh session startup fails 

When a ssh session startup fails, it is useful to know why it has
failed. This commit changes the message from:
   "Failure establishing ssh session"
to something like this, for example:
   "Failure establishing ssh session: -5, Unable to exchange encryption keys"

Closes #3481
