Add force_manual_search to request for case search validation

[stephherbers]

Support Ticket: USH-4011

Product Description

Help performance for vase search validation (has reached 10+ seconds on production)

Technical Summary

Suggested by Shubham, based on the problematic app: "This is because the default_search is set to true for the module (Skip to ES search results) and even though Web Apps passes execute as false , FP perform ES search for modules with default_search set. To override the default_search Web Apps also need to pass the force_manual_search as true for requests where we don’t want to do the search. "
