Merge #11068: qa: Move wait_until to util

Browse Source 
08ce33f8e qa: Move wait_until to util (MarcoFalke)

Pull request description:

  This moves `wait_until` to `util.py` to make it generally available to python tests.
  Also, `wait_until` now takes an optional lock that is acquired while testing the predicate.
  Previously the lock was always acquired, even when it was not necessary, cf. `disconnect_ban.py`.

Tree-SHA512: 18e452a017a6566fa8ad09bde058e1b841e167039dc63299e70cfa7a6dcbc779581e60ca3e8eb2f1b610767d5208b9376c203eb11015b250fd0542b5eb4215a8
