Summary:
Apps usually communicate with multiple hosts to support pops and data centres. The problem currently is that for each host we need a different config in the mock tab in flipper. If the host change due to failover then the mocking stops working. Added support to enter the URL without a host in the flipper. We then check if the Url from the actual network request contains the mock URL without a host.
We can change the hint on flipper UI to suggest either entering the complete URL or without the host to allow matching across multiple hosts.

Let me know if the approach looks good.
