Fix: Wrong performance data values on unit conversion
Fixes an issue with the new check handling, which did not properly convert values from checks to the correct performance data values and base values in some cases
Adds argument `-IntervalInSeconds` for `Enable-IcingaServiceRecovery` to allow setting a custom time interval for the service to restart, while setting the default to 120 seconds (2 minutes)
Fixes EventLog error handling by no longer parsing command arguments to ensure passwords are not stored on the EventLog, unless the debug mode of Icinga for Windows is enable
This adds new and improved handling for Metrics over Time.
The overall execution time for the background tasks has been reduced, while also the memory management is way more efficient.
In addition to the improved core handling of the feature, performance metrics for metrics over time will NO LONGER BE WRITTEN.
This will increase the performance of the graphing solutions like InfluxDB a lot, while the monitoring by using the "-ThresholdInterval" argument is still possible.

Feature: Adds new command to test the functionality of Icinga for Windows
Adds new command `Test-IcingaForWindows`to check the current environment health by also improving internal handlings on how service information are fetched, preventing a lock on those
Feature: Adds support to create snapshot repositories with "New-IcingaRepository"
Adds support to create own snapshot repositories with `New-IcingaRepository`
Feature: Adds renewal handling for Icinga for Windows certificate
Adds automatic renewal of the `icingaforwindows.pfx` certificate for the REST-Api daemon in case the certificate is not yet present, valid or changed during the runtime of the daemon while also making the `icingaforwindows.pfx` mandatory for all installations, regardless of JEA being used or not
Feature: Adds handling to add scheduled task background task
Adds new handling to add scheduled tasks in Windows for interacting with Icinga for Windows core functionality as well as an auto renewal task for the Icinga for Windows certificate generation
