    Reconcile quitting_rpc_timeout with backoff RPC client

    With backoff client, setting .timeout property on it doesn't take any
    effect. It means that starting from Mitaka, we broke
    quitting_rpc_timeout option.

    Now, when the TERM signal is received, we reset the dict capturing
    per-method timeouts; and we cap waiting times by the value of the
    option. This significantly reduces time needed for the agent to
    gracefully shut down.
