* fixes issue https://github.com/Icinga/icinga2/issues/6785 where permission checks get wrong result because permissions checks are done within a shared namespaces without using only unique keys
* mitigates issue https://github.com/Icinga/icinga2/issues/6874 where segmentation faults occur because of concurrent access to non threadsafe parts of namespace (a fix for thread safety of namespaces which would be an alternative approach to get rid of these segfaults is out of scope of this fix as 6785 needs to be fixed anyway and this is the straight-forwards) way to fix that
* do the same for eventqueue (not certain whether events can be processed in parallel but I expect it is the case)

this is a direct fix of the issue revealing the problem that leads to crash
verification done with a patched icinga2 where the execution-order of the code lines of counter-parts involved in re-incrementing/decrementing Timer:Ptr is forced to be the one that leads to the obeserverd segfaults

This follows the same principle as with the shutdown handler,
and was introduced with the changed reload handling with 2.9.
Previously IsShuttingDown() was sufficient which got set at one
location.
SigUsr2 as handler introduced a new location where m_ShuttingDown
is not necessarily set yet. Since this handler gets called when
l_Restarting is enabled, we'll use this flag to avoid config update
events resulting in object deactivation (object->IsActive() always
returns false).

- Better explanation for filters and filter_vars
- Update examples to use filters in the body only, don't fuck around with the URL parameters.
- Better explain actions and their intent
- More insights into config packages and their intention
- Improve API clients and add the tables from icinga2-api-examples
- Formatting for CLI requests

Without this patch, an accidential `\r` in e.g. `$NOTIFICATIONCOMMENT`
leads to a `Content-Type: application/octet-stream` header in e-mails.
The accidential `\r` might slip in usually using Icinga/Nagios apps...
This partially reverts #7150 and avoids exceptions
inside the flow. Each time an empty active stage
is detected, Icinga tries to repair it from the
the given directory tree.
Also, the code now takes into account that it should
create the package storage on startup, whether within
the API object, or if disabled, inside the application.
Caching the active stages for packages in memory
only is in effect with the API feature being enabled.
This is useful for other deployed config packages,
not only the internal one.
