Add support for ignoring deprecations by path

Being able to have deprecations on globally but silence problematic
parts of your application or a noisy plugin that can't be upgraded just
yet allows developers more control when upgrading.

Instead of having to hope they don't add new deprecations they can fix
a part of their application and then remove it from the deprecation
ignore patterns.

I've used glob here instead of regex as I don't think the power of regex
is needed for this.
