### Description
As of today the logic to define high/low priority data sources is missing.
There are situations where we want to deprioritize queries based on them
breaking the time range threshold, but the same cluster might host some data
sources that are higher in priority. For this reason, I've added another
Optional json parameter `exemptDatasources`, which would host those
high-priority datasources, which will skip the deprioritization logic entirely.
Updated the class ThresholdBasedQueryPrioritizationStrategy.
