Implemented multihost database (#9556)
* Hard code a node for non-legacy multidb test
Skip dbengine initialization for new incoming children
Add code to switch to multidb ctx when accessing the dbengine
* When a non-legacy streaming connection is detected, use the multidb metadata log context
* Clear the superblock memory to avoid random data written in the metadata log
* Activate the host detection during compaction
Activate the host detection during metadata log chart updates
Keep the host in the user object during replay of the HOST command
* Add defaults for health / rrdpush on HOST metadata replay
Check for legacy status on host creation by checking is_archived and if not conclusive, call is_legacy_child()
Use defaults from the stream.conf
* Count hosts only if not archived
When host switches from archived to active update rrd_hosts_available
Remove archived hosts from charts and info
* Change parameter from "multidb disk space" to "dbengine multihost disk space"
Remove unused variables
Fix compilation error when dbengine is disabled
Fix condition for machine_guid directory creation under cache_dir
* Enable multidb disk space file creation.
* Stop deleting dimensions when rotating archived metrics if the dimension is active in a different database engine.
* Fix old bug in the code that confused obsolete hosts with orphan hosts.
* Do not delete multi-host DB host files.
* Discard dbengine state when a legacy memory mode instantiates to avoid inconsistencies.
* Identify metadata that collide with non-dbengine memory mode hosts and ignore them.
* Handle non-dbengine localhost with dbengine archived charts in localhost and streaming.
* Ignore archived hosts in streaming.
* Add documentation before merging to master.
