Please split up DecorateFunctionMessage

[mvz]

Use Case

I'm adding checking with rubocop-i18n to an existing code base so there are a lot of offenses. I'd like to fix the low-hanging fruit first, e.g., multi-line strings, and then move on to the more complex work, e.g., eliminating interpolation. The DecorateFunctionMessage cop checks both of these things and more, so slicing up the work becomes harder.

Describe the Solution You Would Like

I'd like to be able to just run a cop that checks for multi-line strings, or interpolation, and also disable each functionality separately in the RuboCop configuration.

Describe Alternatives You've Considered

I'm using grep right now to allow me to only look at multi-line strings, but it feels like a hack and doesn't allow disabling in the RuboCop config.
