Search status field renamed to state.

Previously the status of a search was sometimes called status and sometimes called state depending on the API route. To normalize fields across the entire Baselayer API, the status field has been renamed to state.

Liens and Litigations both come back with a top-level status of their own. In the case of liens it can have a status of Active ,Inactive ,Lapsed, Terminated etc. And similarly a litigation can have a status e.g. Filed, Pending etc.

To differentiate between the top-level status of the object itself and the top-level status of the search (Pending, Executing, Completed, Failed) we have renamed that field to state -> so now once the state of your search enters Completed it is done. This should help differentiate between something related to the response itself (e.g. the status of the lien) and whether or not the search succeeded (the state)
