We can't remove the only Sub from regexp, since the contract for some
operations says that there's at least one Sub, like OpStar or OpPlus.
In order to convert a single-sub element into a no-op, we change the
operation to OpEmptyString.

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:

All the others are more or less utilities and have been moved to `util`:
