A better analyzer warning/error descriptions id prefix?

[Duranom]

Noticed that the warnings/errors generated by the analyzer start with MSG.
Luckily most in past moved away it, it is sadly a not so uncommon prefix with internal solutions and was wondering if instead of MSG prefix a Mediator prefix would not just suffice as it is fast and clear that it is from the library.

Also as side note, the messages seem getting their ids generated in the class making any reorder or removal result in the id's changed breaking any editorconfig file or csproj tags. Having them hard defined would avoid that.

Hmm yes that is a good point, I just started a WIP 4.0 tracking issue and added it to the list: #234
I think it does make sense to prefix it with MEDIATOR or something similar
