SSH configuration

Here is the list of currently supported ssh config options.  Here is the documentation on ssh config options in general including the ones we support. Here is a discussion and example on how to use Match keyword and ProxyCommand. Here's a possible ssh config that uses all options we support:

Host *
    AddressFamily inet
    CanonicalDomains com
    CanonicalizeFallbackLocal no
    CanonicalizeHostname no
    CanonicalizeMaxDots 1
    HostName example.com
    Port 22

Host proxy_server
    User user
    Port 22
    Hostname some_domain

Match host example.com exec not_inside_network
    ProxyCommand ssh -W %h:%p proxy_server
