Update feed test fqmes to use `.<venue>` format

Switch all `test_feeds.py` parametrized fqmes from
legacy `<pair>.<broker>` to the current
`<pair>.<venue>.<broker>` schema (e.g.
`btcusdt.spot.binance`).

Deats,
- update binance fqmes: `btcusdt.binance` ->
  `btcusdt.spot.binance`, same for `ethusdt`.
- update kraken fqmes: `ethusdt.kraken` ->
  `ethusdt.spot.kraken`, `xbtusd.kraken` ->
  `xbtusd.spot.kraken`.
- update cross-broker set similarly.
- comment out old fqmes with `!TODO` to later
  validate raising on bad/legacy formats.

Also,
- reformat `if ci_env and not run_in_ci` to
  multiline style.
- reformat `pytest.skip()` msg to multiline.
- add `?TODO` for symbology helper fn.
- drop stray `await tractor.pause()` in
  `conftest.py`.
