Fixed issue where arguments passed to `compose stop` weren't passed to
the underlying command. Added pg_isready call between each command call
in restore script.
Exec is new command scoped under compose. It allows sending commands
directly into appserver container. I will make this
customizable/controllable in the future.
Implemented custom command builder with nicer api suited for my needs.
Also returned error if there are no containers in
`scripts::postgres::get_containers`.
