Linter: create rule to remove other validation keywords when enum is present based on type

[Karan-Palan]

The rule removes:

• String enum with numeric validation keywords
• Numeric enum with string validation keywords
• Object enum with mixed inapplicable validation keywords

@jviotti any comments?

Your tests, mainly for older versions, are not considering the fact that many of these keywords do not exist in such older versions. For example, minProperties is only present in Draft 4.

The test works because in Draft 0, minProperties is not considered to be a keyword, therefore it applies to "any" type.

However, to make the tests cleaner, can you double check that you are not using any seemingly valid keyword on a Draft version that doesn't actually define it?

To test the above case, we can also have specific new tests that have a non-sense x-foo-bar keyword or something like that, and ensure it doesn't get removed
