Fix MetricsOverTime reporting unknown for checks which do not write performance data
Fixes an issue for certain plugins, like `Invoke-IcingaCheckProcess`, which reports unknown if MetricsOverTime is used for checks that do not write performance data
Fix: Return value for "Agent" component installation failure
Fixes the return value in case the `Agent` component could not be installed from `$FALSE` to `null`
Fix: IfW service installation on certain Windows environment
Fixes Icinga for Windows service installation not working properly on certain Windows environments
Fix: Test commands failing because wrong assigned service data
Fixes test commands like `Test-IcingaForWindows` failing because of wrong assigned ServiceData information.
* Update GetWindowsService.ps1
Instead of repeatedly accessing $SvcData."$ServiceName", store the object in a local variable for better readability.
* Update GetWindowsService.ps1
Fixes code styling

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.

* Set maximum cache duration for service daemons to the right value
This commit sets the maximum duration for cached data for service
daemons to the proper amount.
Previously it was multiplied by 60, probably a typo from a time
when the assigned value was in minutes and not in seconds directly.
Therefore the value was 60 times to high which leads to a massive amount
of cached data which drags down the performance significantly.
* Updates changelog
