Read COMPOSE_FILE from env and use it if it is set. Default is still
docker/local/docker-compose.yaml.
BREAKING CHANGE: Removed docker subcommand. Added deprecation notice to
compose subcommand.
Unified expected output to always eprintln so outputs can be piped to
other processes. Added debug_eprintln and switched all occurances of
debug_println.
Fixed bug where restore commands were called inside pg_isready loop.
Made CommandBuilder::build public. Redirected stdout for pg_isready
calls to /dev/null via Stdio::null().
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`.
