* run cleanup in workers
* when there is a discrepancy between update every, fix it
* fix the other occurences of metric update every mismatch
* allow resetting the same timestamp
* validate flushed pages before committing them to disk
* initialize collection with the latest time in mrg
* these should be static functions
* acquire metrics for writing to detect multiple data collections of the same metric
* print the uuid of the metric that is collected twice
* log the discrepancies of completed pages
* 1 second tolerance
* unify validation of pages and related logging across dbengine
* make do_flush_pages() thread safe
* flush pages runs on libuv workers
* added uv events to tp workers
* dont cross datafile spinlock and rwlock
* should be unlock
* prevent the creation of multiple datafiles
* break an infinite replication loop
* do not log the epxansion of the replication window due to start streaming
* log all invalid pages with internal checks
* do not shutdown event loop threads
* add information about collected page events, to find the root cause of invalid collected pages

* handle multiple collections of the same metric gracefully
* added log about main cache page conflicts; fix gap filling once again...
* keep track of the first metric writer
* it should be an internal fatal - it does not harm users

* prevent negative replication completion percentage
* internal error for the discrepancy of mrg
* better logging of dbengine new metrics collection
* without internal checks it is unused
* prevent pluginsd crash on exit due to calling pthread_cancel() on an exited thread
* renames and atomics everywhere
