Fix warning re: trace_id

This reverts commit 440bd51e08fdfa2a4daa191fb68643456028a753.
dbengine was still being used for non-zero tiers
even on non-dbengine modes.

* make ML work
* Fix compile without NETDATA_INTERNAL_CHECKS
* shutdown each ctx independently
* fix completion of quiesce
* do not update shared ML charts
* Create ML charts on child hosts.
When a parent runs a ML for a child, the relevant-ML charts
should be created on the child host. These charts should use
the parent's hostname to differentiate multiple parents that might
run ML for a child.
The only exception to this rule is the training/prediction resource
usage charts. These are created on the localhost of the parent host,
because they provide information specific to said host.
* check new ml code
* first save the database, then free all memory

* Cleanup metadata thread (part 2)
* increase refcount before dispatching prep command
* Do not try to stop anomaly detection threads twice.
A separate function call has been added to stop anomaly detection threads.
This commit removes the left over function calls that were made
internally when a host was being created/destroyed.

The number of dims per sample is always 1, ie. we are training and
predicting only individual dimensions.
* set the orphan flag when loading archived hosts

* Cleanup metadata thread (part 4)
* Skip metadata host scan when running unittest
* unittest support during init
* dont use all the libuv threads for queries
* break an infinite loop when sleep_usec() is interrupted
* ml prediction is a collector for several charts
* sleep_usec() now makes sure it will never loop if it passes the time expected; sleep_usec() now uses nanosleep() because clock_nanosleep() misses signals on netdata exit
* worker_unregister() in netdata threads cleanup
* moved pdc/epdl/deol/extent_buffer related code to pdc.c and pdc.h
* fixed ML issues
* removed engine2 directory
* added dbengine2 files in CMakeLists.txt
* move query plan data to query target, so that they can be exposed by in jsonwrap
* uniform definition of query plan according to the other query target members
* event_loop should be in daemon, not libnetdata
