Adds an Icinga2 object to directly interface with InfluxDB's native HTTP API.
This supports optional basic authorization, and TLS transport. InfluxDB didn't
appear to like having the TLS stream kept open, so instead this object buffers
data points which are then flushed to InfluxDB as a batch write, either driven
by a configurable timeout or threshold.
As InfluxDB is a schema-less database the host and service templates are user
configurable allowing both the measurement field and tags to be set by the
end user via macro expansion. This allows access to tag fields from arbitrary
data associated with host.vars or service.vars. If a particular value is
unable to be resolved, the tag will be dropped and not transmitted to InfluxDB.
Also alters URL handling to omit array brackets when only a single value is
attached to a key, otherwise InfluxDB has a strop with non-standard syntax.

We cannot add the notification insert id directly
to the following contactnotifications queries. Instead
we need to pass a DbValue reference which gets set after
the notification insert id is calculated.
The contactnotifications insert queries are fired as query
group calling CanExecuteQuery() and FieldToEscapedString().
If the notification id does not exist yet, the queries are
moved to the end of the queue.
Once the contactnotifications queries are fired the DbValue
reference is destroyed.
This patch also removes the old notification insert id cache
which was broken in many ways.

This has been changed when moving comments/downtimes to config objects
in 050c520b2a3df0477f2eec71ec2d874b6dd36aa5
It may cause trouble with DB IDO DELETE and UPDATE statements
depending on the old value.

This patch also moves the next check updates for passive
check results into ProcessCheckResult(). That way the
next check status updates for DB IDO work in a sane way
again.
refs #11336
Only valid for active check results. The API actions were
missing that marker similar to the external command processor.
The initial OK -> NOT-OK transition should use the retry_interval
but nothing else.
