Local configuration files

[danic85]

Each module defined in the config directory has an enabled flag to show whether it should be included or not.
The challenge is that we have multiple instances of this source running, with different modules enabled.

I'd like to have a local instance configuration that overrides the enabled flags for each of the modules.

The code is stored in github and I'd like the module yml files to be stored in github, but whether they are enabled (and some config information like pin changes etc) should be overrideable at a local instance level.

Example: Local Override (config/overrides/vision_imx500.local.yml)

vision_imx500:
  enabled: false
  config:
    preview: true
    pin: 22

This would then disable the module, even if it is enabled in the main vision_imx500.yml file. The config element is optional and would only be included if a change is required at an instance level.

I have created a PR to manage this, but I'm not convinced that my mutagen ignore file is working. Without that the local overrides will be synced with all my robots, rather than remaining local to each one.

#142

I'll continue testing, but pushing this up for others in case it is useful to override some of the config changes in develop as I work on Cody.

Closing this as we now have environment defines to allow this.
