CLI Improvements

[NeonDaniel]

As discussed in #24

• Add flag to specify the module to get config for (respecting submodule_mappings in config)
• Add flag to specify a module (respecting module_overrides in config)
• Add CLI option to print (modify?) meta config

from the other PR comments

Maybe for a future PR, this needs an option to show different base directories/config filenames. I'd propose adding flags:

-m/--module: Module to get config for

Under the hood, this has to read submodule_mappings

-o/--override: Get config for a specific module

Arg passed here should be a valid key under module_overrides, otherwise return error

Also, another command might be useful: meta: Show meta config (ovos.conf)

we should move/deprecate the OCA utils too, so OCA is just the web ui
