If LazyState cannot parse the attributes of its row as JSON, it prints
a message to the logger. Unfortunately, it passes `self` as a format
argument to that message, which causes its `__repr__` method to be
called, which then tries to retrieve `self.attributes` in order to
display them. This leads to an infinite recursion and a crash of the
entire core.
To fix, send the database row to be printed in the log message, rather
than the LazyState object that wraps around it.
* Prebake common history queries
The python overhead of to construct
the queries exceeded the database overhead. We now
prebake the queries that get frequently polled.
This reduces the time it takes to update history_stats
sensors and can make quite a difference if there
are a lot of them.
When using the mini-graph-card card, all the entities
on the card being graphed are queried every few seconds
for new states. Previously this would tie up the database if there
are lot of these graphs in the UI.

* cache entity_filter in the lambda
* switch to yield
* Revert "switch to yield"
This reverts commit f8386f4940.
* get_states always returns a list
* query wasnt actually reusable so revert part of the breakout

* fixed formatting issue from rebase/conflict
* Checking against glob patterns in more performant way
* perf improvments and reverted unnecessarily adjusted tests
* added new benchmark test around filters
* no longer using get with default in entityfilter
* changed filter name and removed logbook from filter benchmark

* fixed azure test and clean up for other tests
* renaming test files to match standard
* merged mqtt statestream test changes with base
* removed dependency on recorder filter schema from history
* fixed recorder tests after merge and a bunch of lint errors
Cleanup indexes as >50% of the db size was indexes,
many of them unused in any current query
Logbook search was having to filter event_types without
an index:
Created ix_events_event_type_time_fired
Dropped ix_events_event_type
States had a redundant keys on composite index:
Dropped ix_states_entity_id
Its unused since we have ix_states_entity_id_last_updated
De-duplicate storage of context in states as
its always stored in events and can be found
by joining the state on the event_id.
Dropped ix_states_context_id
Dropped ix_states_context_parent_id
Dropped ix_states_context_user_id
After schema v9:
STATES............................................ 10186 40.9%
EVENTS............................................ 5502 22.1%
IX_STATES_ENTITY_ID_LAST_UPDATED.................. 2177 8.7%
IX_EVENTS_EVENT_TYPE_TIME_FIRED................... 1910 7.7%
IX_EVENTS_CONTEXT_ID.............................. 1592 6.4%
IX_EVENTS_TIME_FIRED.............................. 1383 5.6%
IX_STATES_LAST_UPDATED............................ 1079 4.3%
IX_STATES_EVENT_ID................................ 375 1.5%
IX_EVENTS_CONTEXT_PARENT_ID....................... 347 1.4%
IX_EVENTS_CONTEXT_USER_ID......................... 346 1.4%
IX_RECORDER_RUNS_START_END........................ 1 0.004%
RECORDER_RUNS..................................... 1 0.004%
SCHEMA_CHANGES.................................... 1 0.004%
SQLITE_MASTER..................................... 1 0.004%
