Console commands

[rwstauner]

We could define common commands in module definitions.

Then you could do muss console psql (or muss console db or whatever you want to call it)
instead of muss run postgres psql or psql -h $dockerhost -p $exposedport -U $whatuserisit

If we used this instead of using psql directly then you wouldn't need to expose global ports and could avoid port conflicts that come from running too many projects.

A good default console command could be:

console_default_command: [sh, -c, 'exec `command -v bash || echo sh` "$@"', --]

so that muss console container-name would default to bash and fallback to sh if nothing more specific was defined

[rwstauner]

maybe a --run arg to use run instead of exec?
or

console_prefer_run: true

?
