DBENGINE v2 - improvements part 10 (#14332)
* replication cancels pending queries on exit
* log when waiting for inflight queries
* when there are collected and not-collected metrics, use the context priority from the collected only
* Write metadata with a faster pace
* Remove journal file size limit and sync mode to 0 / Drop wal checkpoint for now
* Wrap in a big transaction remaining metadata writes (test 1)
* fix higher tiers when tiering iterations = 2
* dbengine always returns db-aligned points; query engine expands the queries by 2 points in every direction to have enough data for interpolation
* Wrap in a big transaction metadata writes (test 2)
* replication cancelling fix
* do not first and last entry in replication when the db has no retention
* fix internal check condition
* Increase metadata write batch size
* always apply error limit to dbengine logs
* Remove code that processes the obsolete health.db files
* cleanup in query.c
* do not allow queries to go beyond db boundaries
* prevent internal log for +1 delta in timestamp
* detect gap pages in conflicts
* double protection for gap injection in main cache
* Add checkpoint to prevent large WAL while running
Remove unused and duplicate functions
* do not allocate chart cache dir if not needed
* add more info to unittests
* revert query expansion to satisfy unittests
