(Feature request) Enable to set "ServerAliveInterval" configuration for ParamikoSSHClient

[userlocalhost]

I hope ParamikoSSHClient would be expanded to be able to set following configurations from the SSH client's configuration file, which is specified at ssh_runner.ssh_config_file_path in the st2.conf.

1. ServerAliveInterval
2. ServerAliveCountMax (But, unfortunately, Paramiko hasn't implemented feature that is equivalent with this option yet, according to this issue)

These (especially for "ServerAliveInterval") are necessary for the use-case that is difficult to change the sshd configuration on the host(s) that core.remote targets and channel quality is not steady between them.
