This commit disables some unused workflows on our CI.
Also uses grafana/regexp instead of regexp which is blackisted.
Also updates head_test TestHeadReadWriterRepair increasing
ChunkWriteQueueSize to 1 so that the chunk disk mapper uses the async
queue. This seems to be default behaviour in upstream prometheus and
without this option our test fails.
This creates a new `model` directory and moves all data-model related
packages over there:
exemplar labels relabel rulefmt textparse timestamp value
All the others are more or less utilities and have been moved to `util`:
gate logging modetimevfs pool runtime
