* Core/Metric: Log detailed metrics about each opcode handler
* Add new panel to Performance profiling dashboard and use fill(0) instead of fill(none)
* Add new settings Metric.Threshold.* to be able to specify the minimum threshold for the specified metrics
* Update dashboard
* Change thresholds to be required to send the metrics. A TC_METRIC_DETAILED_TIMER metric with an expected threshold not configured will be ignored
* Use typedef Milliseconds
* Refresh realms on load
(cherry picked from commit 8a2c79c850)
* Core/Metric: Add more metrics about World::Update() loop
* Add new Performance profiling grafana dashboard
* Add new cmake setting WITHOUT_METRICS that disables all metrics
As new metrics are added, someone might want to disable them if unused.
* Add more metrics about World::Update() loop
* Remove old performance profiling features
Remove "server set difftime" command, "-RecordUpdateTimeDiffInterval" and "MinRecordUpdateTimeDiff" worldserver config settings and their related code.
The whole UpdateTime class could be removed too.
* Update and rename 2020_07_99_99_world.sql to 2020_07_24_00_world.sql
(cherry picked from commit 3c0ac7302f)

* Add more performant version to reduce allocations when metrics are disabled
* Linux build fix
* Add metric stopwatch version that doesnt let users forget to _END it
* Fix linux build
* Code cleanup
* Add Map updates panel to General dashboard
* Add "Recent events" panel to General dashboard

(cherry picked from commit 4e1dbd1cf8)
Fix a memory leak in Metric happening only when enabling/disabling Metric from configs at runtime, leaking the metric added between last SendBatch() call and the ScheduleSend() call in the same function. The only way to reproduce this is to actually freeze the thread calling SendBatch(), disable metric, reload config, unfreeze the thread.

* Common/Graphs: Initial proof of concept
* Move influx db code to its own class
* Reuse the same socket
* Allow to log values of different categories
* Allow to log events
* Pass the timestamp to influxdb
* Send events in batches
* Send data async
* Log server shutdown.
Fix memory leak.
* Allow to enable/disable Stats in the settings and at runtime
* Read interval between each batch send from config
* Add InfluxDB connection info to configs
* Move each event category to its own table
* Log pathfinding queries
* Move categories table initialization to constructor using enum as key to avoid assigning the table name to the wrong enum value
* Log player login/logout events.
Pass the hostname correctly in the HTTP request.
* Fix linux build
* Handle "Connection: close" HTTP header, reconnecting on next scheduled send.
Disable StatsLogger if connection fails, logging the error.
* Add an enum for categories of logged values, it's still possible to pass a string instead of the enum.
* Don't log the whole batchedData when InfluxDB returns an error, it's too long and unreadable on console.
* Allow to call a function at a specified interval in thread-safe World::Update() context to log data like player count.
* Log map tile load/unload
* Core/StatsLogger: Allow logging more value types other than ints
https://docs.influxdata.com/influxdb/v0.10/write_protocols/write_syntax/
* Fix a typo in string escape of StatsLogger
* Yet more fixes to the escaping in FormatInfluxDBValue
* DB/Gameobject: Fix respawn time of few Quest GameObjects
By Tauriella, closes#16701
* DB/Misc: Fix some engrish
By tkrokli closes#16648
* Tools/MMaps: Add format library linking to mmaps_generator
(Very) partial cherry pick of ed75b0649a
* Core/StatsLogger: Simplify code
Convert values and categories arrays to maps initialized in-place
Remove constructor and destructor
* Core/StatsLogger: Add realm name to the event and value tags
* Log amount of processed packet of each session
* Apply recent singleton changes to sStatsLogger too
* Fix influxdb data format if no realm name is present
* Remove unneeded newlines from request body, fixes response 400 from InfluxDB 0.10
* Rename Reporting folder to Metric
* Rename StatsLogger to Metric
* Rename InfluxDB configs to Metric
* Add Grafana dashboards
* Add a random annoying macro
* Move string formatting to Metric::SendBatch(), reducing performance footprint of Metric::LogEvent() and Metric::LogValue()
* Update grafana graphs refresing tags on load and showing now-15m data, refreshing every minute. These settings can be modified in grafana.
* Rename MetricData fields
* Contrib/Grafana: Rename dashboard files
* Contrib/Grafana: Replace hardcoded Windows/Ubuntu realm names by the default, Trinity
* Config/Worldserver: Add missing section to the index
* Contrib/Grafana: Add singlestat panels with current online players, update diff averages (1 min, 5 mins and 15 mins)

* Core/Metric: Replace the enums MetricEventCategory and MetricValueCategory by strings
For the sake of simplicity and less recompile time when adding new metrics, similar to how TC_LOG_* works
* Contrib/Grafana: Display the current number of online players and not its average
