Diff and update mobile configs

Summary:
This diff makes it possible to apply MC's to a currently running as part of the support form process.

Things _NOT_ done in the diff:

* make sure getUniverses and getGatekeepers returns valid configs (this broke since somewhere last week, opened T57918601 for that. However, before that this worked correctly
* provide a more interactive UI when applying MC's, such as beeing able to see a diff preview, ask confirmation before overriding current config, etc
