Replaces Get-EventLog with Get-WinEvent

[LordHepipud]

Replaces the deprecated function Get-EventLog with Get-WinEvent. In addition, the plugin received a new argument -MaxEntries to allow additional filtering for the number of events fetched to improve performance in addition. The EventLog now also supports an array with list items, allowing easier filtering for severities which are allowed inside the EventLog.

The PR is working great so far. Now we can access all eventlogs.

I made the observation, that with the new version IncludeSource needs to be quoted, if spaces are present. Otherwise an exception occures. Not sure if this is a bug or not.

before: (framework: 1.4.1, plugins: 1.4.0)

icinga> Invoke-IcingaCheckEventlog -LogName System -IncludeEventId 7024 -IncludeSource Service Control Manager -Maxentri
es 3000 -warning 1 -critical 1
[OK] Check package "EventLog"
|
0

after: (framework: current master, plugins: this pr)

exception without quotes

icinga> Invoke-IcingaCheckEventlog -LogName System -IncludeEventId 7024 -IncludeSource Service Control Manager -Maxentries 3000 -warning 1 -critical 1
Exception calling "Translate" with "1" argument(s): "Some or all identity references could not be translated."

I still need to test with the new and the old version, if I get the same results. I do this later.

The filtering for eventid and eventsource is also working as expected.
You did great work here 💯
