Implement matching files to suites

This adds the "glob" based pattern matching so overlord can map files to suites. Path matching should be moderately smart as we find the "deepest" root in which the path could possibly be located.

An example:

Roots:
`/a/b/`
`/a/b/c/d`
`/a/b/c`
`/a/b/c/d/e/f/g`

If your path is something like`/a/b/c/foo_test.js` we will only search the patterns of /a/b/c (globs should be the slowest part of this so we attempt to only use them in the folders we need to).
