Add setUrlParams utility

What does this MR do?

This adds the setUrlParams method to our url_utility.

The utility methods adds new query params, updates existing params with a new value and removes params with value null/undefined from the given URL.

In addition, when clearParams=true, it removes all existing query params from the URL before setting new params.

This utility will be used later in !21390 (merged)
