--------------------------------------
Created PR of the enhancement. PFA: [GitHub Pull Request
#535|https://github.com/apache/ofbiz-framework/pull/535]
Optimized the 'get average product rating' method logic.
Done following:
- Enhanced and optimized the OOTB 'get average product rating' method logic and
updated its references.
- Updated the 'get average product rating' method logic and optimized the logic
by using dynamic entity using 'average' function to get the average rather than
iterating all the product reviews.
- Updated the service parameter and updated all the references to add
'delegator' as the new parameter.

> *#Problem*: When calculating the average product rating for any product, the
> 'get average product rating' method first retrieves the whole list of reviews
> and then iterates all product reviews to determine.
> The approach takes time to respond when there are thousands of reviews of a
> single product. It takes significantly longer to display many products
> together with their reviews. (e.g. search result page)
> *#Solution*: We can use the 'average' function to get the average rather than
> iterating all the product reviews.
