feat(ssh): support ProxyCommand, Include, Match, and none auth from ~/.ssh/config (#1704)

Read Include, Match (host/user/exec), Key=Value, ProxyCommand with % tokens, StrictHostKeyChecking and UserKnownHostsFile from ~/.ssh/config, connect over a ProxyCommand's stdio, and try none authentication first in OpenSSH mode. accept-new records unknown host keys and still refuses changed ones; Match exec runs off the async runtime with a 10 s limit.
