[Security Solution][Exceptions] Notify users of outdated exceptions

[yctercero]

Describe the feature:

When a user creates an exception that uses large value lists, we check that the field selected matches the type of the list. So only large value lists of type keyword appear for keyword fields, large value lists of type ip for ip fields, etc...

If a user update their mapping from keyword/text to just keyword when they revisit their exceptions it would appear as if though their lists are no longer there (because of the type mismatch that now exists).

Describe a specific use case for the feature:
Alerting the user with a badge that warns them of this on exceptions where we see there is now a mismatch would be extremely helpful. Unless a user checks their exceptions, they may not realize that the exception is no longer valid.

Note: Recent case of user running into this issue. Initially thought it was a bug with exceptions, but was a mapping issue described above.
