Usage: snail ssh copy-id [options] <fake_host>

add a local public key to authorized keys in project

Options:
  -i <identity_file>  specify which public key file
  -h, --help          display help for command

This is like ssh-copy-id. It's not as intelligent though. It unconditionally
adds the public key without trying to authenticate first. Also it does not
support ssh-agent.

The fake_host is the project domain, optionally followed by a dot and
additional labels, which Snail ignores.
