CLI was failing to connect during TPU provisioning with following error:

dstack._internal.core.errors.SSHError: Can't connect to the remote host

Discussed Solutions:

1. Increasing the ConnectTimeout value in SSH_DEFAULT_OPTIONS eg: 10 instead of 3.

2. Disable SSH options by passing options={}.

Implemented Solution
Option 2 is recommended and implemented because it resembles the settings before Commit
