Add support for specifying a different ssh configuration file

[btm]

Describe the Enhancement:

Allow specifying a ssh configuration other than the default file

Describe the Need:

Allows the use of managed and/or templated ssh configuration files for a company that are maintained separate from the individual users ~/.ssh/config file.

Net::SSH::Config.for(host) allows passing a path to a non-default configuration file. A --ssh-config option could be added to specify that file and pass it in ssh_config_for_host.
