DBENGINE v2 - improvements part 11 (#14337)
* acquiring / releasing interface for metrics
* metrics registry statistics
* cleanup metrics registry by deleting metrics when they dont have retention anymore; do not double copy the data of pages to be flushed
* print the tier in retention summary
* Open files with buffered instead of direct I/O (test)
* added more metrics stats and fixed unittest
* rename writer functions to avoid confusion with refcounting
* do not release a metric that is not acquired
* Revert to use direct I/O on write -- use direct I/O on read as well
* keep track of ARAL overhead and add it to the memory chart
* aral full check via api
* Cleanup
* give names to ARALs and PGCs
* aral improvements
* restore query expansion to the future
* prefer higher resolution tier when switching plans
* added extent read statistics
* smoother joining of tiers at query engine
* fine tune aral max allocation size
* aral restructuring to hide its internals from the rest of netdata
* aral restructuring; addtion of defrag option to aral to keep the linked list sorted - enabled by default to test it
* fully async aral
* some statistics and cleanup
* fix infinite loop while calculating retention
* aral docs and defragmenting disabled by default
* fix bug and add optimization when defragmenter is not enabled
* aral stress test
* aral speed report and documentation
* added internal checks that all pages are full
* improve internal log about metrics deletion
* metrics registry uses one aral per partition
* metrics registry aral max size to 512 elements per page
* remove data_structures/README.md dependency
