add keep-alive support on ssh session when connecting to postgresql server over ssh-tunnel

[exedx7]

Possibility of configuring ssh tunnel with keep-alive feature.

Connection->properties windows -> tab: 'SSH Tunnel'
Add row in the input form and apply non zero value to the ssh session settings.
Keep-Alive interval (sec) 0 (means no-keep-alive enabled), >0 keep-alive enabled

No alternatives

Without K-A when we have connection over ssh-tunnel we can face with the situation that connection is dropped in case timeout of inactivity is configured on ssh-server site (ClientAliveInterval>0).
