Added a 'deploy' command to the dcil interface

Often times I want to compile, deploy to a remote system and run a dcli script.

the ideal is to create a new command deploy that can do these three actions in one line

dcli deploy bin/someapp.dart --remote host.domain.com.au  --protocol=<ssh| ftp |http|...> --port=<optional port> --path=<remote path> --run --- <args to someapp>

So the command would
compile bin/someapp.dart
copy it to 'host.domain.com.au' using the selected protocol (defaults to ssh)
uses the --port which defaults based on protocol
the command is copied to the <remote path>
runs the command on the remote host passing in the <args to someapp>

The remote run will only work with ssh
Are the other protocols worth supporting?

It would be nice if we could save the arguments to a config file associated with the script and have an option to re-use the configured commands.

The issue does not name files or tests; start by locating the dcli command interface and the existing compilation and remote-copy entry points. Clarify the supported protocol scope, SSH-only execution behavior, argument forwarding, and config-file reuse before defining what completion and tests should cover.
