Stefan Agner f0006b92be Allow to lock SQLite database during backup (#60874) ...

* Allow to set CONF_DB_URL

This is useful for test which need a custom DB path.

* Introduce write_lock_db helper to lock SQLite database

* Introduce Websocket API which allows to lock database during backup

* Fix isort

* Avoid mutable default arguments

* Address pylint issues

* Avoid holding executor thread

* Set unlock event in case timeout occures

This makes sure the database is left unlocked even in case of a race
condition.

* Add more unit tests

* Address new pylint errors

* Lower timeout to speedup tests

* Introduce queue overflow test

* Unlock database if necessary

This makes sure that the test runs through in case locking actually
succeeds (and the test fails).

* Make DB_LOCK_TIMEOUT a global

There is no good reason for this to be an argument. The recorder needs
to pick a sensible value.

* Add Websocket Timeout test

* Test lock_database() return

* Update homeassistant/components/recorder/__init__.py
