* kickoff txt registry * fix inmemory dns provider to include recordtype info for validation * Merge master * fix ununsed variable in inmemory provider * add tests for records * add test for no prefix name formatter * implement apply changes with tests * add flag to enable txt registry * add txt registry to main * improve sort testing * filter out non-owned records * NewEndpoint(...) requires record type * use newendpoint in aws_test, fix tests * change suitable type implementation * fix the test for compatibility component * change inmemory provider to include recordtype and use suitable type * fix comments, CNAME should target hostname * name mapper do not use pointer on struct * txt prefix - just concatenate, remove spew, fix txt record label * allow TXT records as result from dns provider * add changelog * fix tests * TXT records need to be enclosed in double quotes
