Add tags schema with full table replication strategy to track releases

[fow5040]

Added basic support for tags for github repos - all tags will be replicated on each run of the tap for a given repo.

Currently tracking the following for tags: { "name", "zipball_url", "tarball_url", "commit": { "sha", "url" }, "node_id" }
