Version 1.1.9-251217

ADDED
- [FILTER_BY_SERVICE_LABEL] section.
  This option now allows you to filter what goes into the topology at the interface level. Simply add service labels to the interfaces you want to filter and configure NVDCT accordingly.
```
[FILTER_BY_SERVICE_LABEL]
"nvdct/l2_include:yes" = "INCLUDE"
"nvdct/l2_include:no" = "EXCLUDE"
```
And yes, you can have as many labels as you need/whish.
CHANGED
- Replaced the MonitoredHost/MonitoredService form_specs with String in the active check rule set.
  Why? → [BUG] (or by design?) form_spec MonitoredHost doesn’t work as expected
  So you have to type the correct host/service names your self now. The input validation will still check if the host/service exists.

Note: the next version will finaly remove the deprecated options --time-format/--update-config and raise the minimum required Checkmk version to 2.3.0p31/2.4.0b4. In addition, I plan to begin preparations for the upcoming Checkmk version 2.5. This will also require updating the inventory plugins.
