Validate global options too

[akx]

This PR contains a:

• bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

I noticed #419 added validation for the patterns array, but the global options (which are touched by e.g. #435) aren't validated. (I may or may not have banged my head against the wall there.)

The documentation was also updated to reflect the fact that one can actually pass in Minimatch settings objects for ignore too.

Breaking Changes

This may break some downstream software misusing the options object.

Additional Info

"Test update" is not checked, because tests don't pass in naughty options.

Can you update jest to avoid npm problem too?

Can you update jest to avoid npm problem too?

@evilebottnawi No, that was discussed in the comment in #438 – updating Jest (via npm audit --fix) breaks compatibility with Node 6 and Node 8 since it begins using native async/await. Dropping Node 6 and Node 8 is discussed in #412.

Thanks for the PR, we will remove global options in the next major release, because we already remove logLevel (we use built-in webpack logger you can setup level using webpack config) and copyUnmodifed options (it was bad design we need persist assets between builds), so I am closing this PR, I start to removing global options support
