separate module configs for different api versions

[nclundsten]

this is all related to how the underlying code of the ui reads/writes the api configs for versions to module.config.php

currently:
a src/Rest/V1/Rest and a src/Rest/V2/Rest have shared config in
module.config.php

proposed change would be something like:
src/Rest/V1/Rest with a config/module.v1.rest.config.php
src/Rest/V2/Rest with a config/module.v2.rest.config.php

this would allow for easy drop-in/removal of api versions
by just merging the extra config in Module.php::getConfig()
