* add hosts middleware * forgot pointer receiver * add appropriately modified hostsfile tests from golang repo * remove test artifacts, separate hostsfile parsing from caching and opening, remove unused metrics references, move middleware up the chain * refactored the logic for creating records and filtering ip address versions. also got PTR lookups working * Add README.md. Modify config to be more concise. Add zones list to config. Filter PTR responses based on zones list. * add Fallthrough and return correct dns response code otherwise * Simplified Hostsfile to only store hosts in the zones we care about, and by ip version. Added handler tests and improved other tests. * oops, goimports loaded a package from a different repo
