Limitation by branch

[dchubar-fj]

Problem/Motivation

The ability to set the default branch is very helpful if you want to display Activity Finder on branch-related pages.

Proposed resolution
Add a new Branch autocomplete field to the Activity Finder block. If the field is not empty we should do the following:

• Skip all steps and display results step
• Hide the filter by branch and display results only for the specific branch should be displayed.
• Should work for both back-ends: Solr and Daxko
