feat: add config for the format command

[jkoenig134]

Description

Added a configuration for the melos format command to manage lineLength and setExitIfChanged using the config.

CLI input will overwrite the config values, but if config states true for setExitIfChanged it cannot be overwritten b/c --set-exit-if-changed is not negatable.

Just one minor nit

@spydon do you already have plans when this is released?

@spydon do you already have plans when this is released?

We're trying to land #702 and then do a release. Currently I'm a bit sceptical of those priority groups, I'd rather just have a name for the second priority group and not have the first one at all, and then have the argument name based on that. But we haven't been able to come up with a good name yet, maybe you'd have some suggestion if you had a look? :)

@spydon I don't think I know what's going on there, but I can try to get into it.
