Merge pull request #1028 from kbarber/ticket/master/pdb-709-new-fact-path-value-querying

(PDB-709) Fact nodes endpoint
(PDB-746) Add capability to use globs when querying fact-nodes

This adds the new operator ~> which is a path glob operator that only works
against the `path` type. It works by internally converting the array of
literals and potential globs into a single regular expression for querying
the fact paths.
