Get-RubrikEvent and EventSeriesId

[mwpreston]

Current Behavior:

Currently the only way to retrieve a list of events inside an eventSeries is to use Get-RubrikEvent, passing the eventseriesid parameter as well as setting ShowOnlyLatest to false.

This process takes a looong time to complete. This is caused by the API endpoint (/event) querying the event table and performing a full scan. Most the time this will simply error out.

Rather than using the /event api, the /event_series endpoint can be utilized. /event_series queries the events_by_series table which has the proper primary keys defined to make this search faster.

Would like to see a cmdlet created (Get-RubrikEventSeries) which will retrieve this information from the event_series endpoint. When Get-RubrikEvent is called with an eventSeriesId parameter, the cmdlet can simply call the Get-RubrikEventSeries to get the valid results.
