Add gpg_fingerprint lookup and filter (#639)

Browse Source 
* Add gpg_fingerprint lookup.

* Work around problems on some CI targets.

* Use get_bin_path to find the gpg executable. Document that we need it.

* Improve and test error handling.

* Refactor (potentially) common code to module_utils and plugin_utils.

This will be useful to create a filter version of this, and further lookups, filters, and modules.

* Do not create a keyring when there isn't one.

* Fixups.

* Fix description.

* More fixes for lookup.

* Also add a gpg_fingerprint filter.

* Improve formulation.
