    Convergence: Store resource status in cache data

    Fix failing convergence gate functional tests
    - store resource uuid, action, status in cache data. Most of the code
    requires the resource to have proper status and uuid to work.
    - initialize rsrc._data to None so that the resource data is fetched from
    db first time.
