WA2 only supported a single config file but the way WA3's configuration
parser works there can be as many and the user needs. They will be prioritied
in the order they are specified. e.g in `wa run agenda.yaml -c 1.yaml -c 2.yaml`
`1.yaml` will be applied first and `2.yaml` will be applied on top of that.
In the process removed modules and boot_strap.py. Also Renamed extensions Plugins.
Louie is now monkey patched rather than containing a modified version in external
- standardisded on a single context argument
- removed Device.init() no longer necessary as initilize now
automatically gets propagated up the hierarchy. Renamed the existing
use of it to "initilize".
- related pylint cleanup.
