I agree, I will drop the selftest in V4.

The selftest have been very useful during *development* phase.
The number of options also reveal that we (Jonas and I) have been using
this beyond a selftest. The veth_bql_test_virtme.sh wrapper have been a
huge help to accelerate test-based development cycles,  but it's not a
selftest component per say. This have caught actual bugs in our BQL/DQL
API usage, but all those BUGs are fixed in code.

It makes a lot of sense to avoid having to maintain this code in tree.
I can place it somewhere on GitHub, else it can be pulled from lore.
