QUERY_TARGET: new query engine for Netdata Agent (#13697)
* initial implementation of QUERY_TARGET
* rrd2rrdr() interface
* rrddim_find_best_tier_for_timeframe() ported
* added dimension filtering
* added db object in query target
* rrd2rrdr() ported
* working on formatters
* working on jsonwrapper
* finally, it compiles...
* 1st run without crashes
* query planer working
* cleanup old code
* review changes
* fix also changing data collection frequency
* fix signess
* fix rrdlabels and dimension ordering
* fixes
* remove unused variable
* ml should accept NULL response from rrd2rrdr()
* number formatting fixes
* more number formatting fixes
* more number formatting fixes
* support mc parallel queries
* formatting and cleanup
* added rrd2rrdr_legacy() as a simplified interface to run a query
* make sure rrdset_find_natural_update_every_for_timeframe() returns a value
* make signed comparisons
* weights endpoint using rrdcontexts
* fix for legacy db modes and cleanup
* fix for chart_ids and remove AR chart from weights endpoint
* Ignore command if not initialized yet
* remove unused members
* properly initialize window
* code cleanup - rrddim linked list is gone; rrdset rwlock is gone too
* reviewed RRDR.internal members
* eliminate unnecessary members of QUERY_TARGET
* more complete query ids; more detailed information on aborted queries
* properly terminate option strings
* query id contains group_options which is controlled by users, so escaping is necessary
* tense in query id
* tense in query id - again
* added the remaining query options to the query id
* Expose hidden option to the dimension
* use the hidden flag when loading context dimensions
* Specify table alias for option
* dont update chart last access time, unless at least a dimension of the chart will be queried
