ANSUPDATE-129 Patch SSH config for timeouts

Adding execution of a script to add configuration to the local system
SSH client configuration file that engages a heartbeat mechanism that
allows SSH to know that the server is still alive instead of relying
on inactivity to declare the SSH connection as failed.  These SSH
timeout issues present themselves as Broken Pipe errors.

Long running scripts, such as the database creation/upgrade scripts
can cause the SSH connection to go idle for a period of up to several
minutes with no output.
