Add support for MDM with the following keys:

Tests

Cannot test using a real MDM configuration, but can be tested by hacking the method getData to return a custom string.
I have tested by returning a value for MdmData.DefaultHomeserverUrl different from matrix.org and the application was correctly defaulting to the provided homeserver.

Also currently when the MDM configuration change, this is a no-op on the application. We may consider logging out the user.

One change on the DI otherwise LGTM

[ganfra]

You should use @Singleton otherwise listeners won't be kept.
Also use @Binds instead of @Provides

Done in 6452b5c, hence I think it was fine since the listener was added and removed by the same entity (the Activity).
OK for you?
