Subject: [PATCH 2/2] Update the client to include shorthand options

Providing aliases for all of the supported options
-h, --host
-s, --subdomain
-l, --local-host
-o, --open
-p, --port
--help
--version

Minor clean up in the code removing the blocks that already handled
by yargs ( version, help and required options )

Handle validating that the passed port could be validated as a number

Remove the spaces in empty lines
