Jon Siwek 99c89b42d7 Internal refactoring of how plugin components are tagged/managed.
Made some class templates for code that seemed duplicated between
file/protocol tags and managers.  Seems like it helps a bit and
hopefully can be also be used to transition other things that have
enum value "tags" (e.g. logging writers, input readers) to the
plugin system.
