/api/v2/contexts (#14592)

* preparation for /api/v2/contexts

* working /api/v2/contexts

* add anomaly rate information in all statistics; when sum-count is requested, return sums and counts instead of averages

* minor fix

* query targegt now accurately counts hosts, contexts, instances, dimensions, metrics

* cleanup /api/v2/contexts

* full text search with /api/v2/contexts

* simple patterns now support the option to search ignoring case

* full text search API with /api/v2/q

* simple pattern execution optimization

* do not show q when not given

* full text search accounting

* separated /api/v2/nodes from /api/v2/contexts

* fix ssv queries for group_by

* count query instances queried and failed per context and host

* split rrdcontext.c to multiple files

* add query totals

* fix anomaly rate calculation; provide "ni" for indexing hosts

* do not generate zero valued members

* faster calculation of anomaly rate; by just summing integers for each db points and doing math once for every generated point

* fix typo when printing dimensions totals

* added option minify to remove spaces and newlines fron JSON output

* send instance ids and names when they differ

* do not add in query target dimensions, instances, contexts and hosts for which there is no retention in the current timeframe

* fix for the previous + renames and code cleanup

* when a dimension is filtered, include in the response all the other dimensions that are selectable

* do not add nodes that do not have retention in the current window

* move selection of dimensions to query_dimension_add(), instead of query_metric_add()

* increase the pre-processing capacity of queries

* generate instance fqdn ids and names only when they are needed

* provide detailed statistics about tiers retention, queries, points, update_every

* late allocation of query dimensions

* cleanup

* more cleanup

* support for annotations per displayed point, RESET and PARTIAL

* new type annotations

* if a chart is not linked to contexts and it is collected, link it when it is collected

* make ML run reentrant

* make ML rrdr query synchronous

* optimize replication memory allocation of replication_sort_entry

* change units to percentage, when requesting a coefficinet of variation, or a percentage query

* initialize replication before starting main threads

* properly decrement no room requests counter

* propagate the non-zero flag to group-by

* the same by avoiding the extra loop

* respect non-zero in all dimension arrays

* remove dictionary garbage collection from dictionary_entries() and dictionary_version()

* be more verbose when jv2 indexing is postponed

* prevent infinite loop

* use hidden dimensions even when dimensions pattern is unset

* traverse hosts using dictionaries

* fix dictionary unittests
