New Feature: Query Elevation on "fq" field.

[Mouhcine Boutinzer]

Hi there,
I am planning to suggest/introduce a new Query Elevation feature to Solr.
Currently, Solr supports Query Elevation for query parameter only (aka "q").
What I suggest is to allow users to set a Query Elevation configuration for
filter query parameter as well (aka "fq").
I am willing to create a JIRA issue for that, but I thought it might be
better if I communicate the idea to the dev team before submitting my issue.
Many thanks.
