Fix to register priority function ResourceLimitsPriority correctly.

**What this PR does / why we need it**:
This PR fixes registration of priority function ResourceLimitsPriority.  Previously this function was being registered inside `init()`. Since this priority function ResourceLimitsPriority is behind feature gate `ResourceLimitsPriorityFunction` and if the feature is enabled, it was not visible in `init()` function. So now the registration of this priority function is moved inside `ApplyFeatureGates()` in scheduler where it can be correctly registered after the feature has been enabled.
