[ihc] Improved command handling when controller is not ready (#10895)

* [ihc] Improved command handling when controller is not ready

When connection from binding to IHC controller is open, but controller
is in programming state, things state is offline with special status to
indicate that binding can't send or receive any resource updates at the
moment. Things status check during command sending will prevent
unnecessary resource updates which will eventually fail and binding then
tries to restart the connection.
