> This occurs when status command response is received after start of next
> stage which modifies sch state (quite often on starting services during
> install).
> # status command is sent to agent (happens every 60 seconds)
> # start commands are scheduled, generated event which move sch from INSTALLED
> to STARTING
> # status command response received from agent. sch status directly set to
> INSTALLED bypassing state machine
> # All subsequent task reports from agent trigger InvalidTransitionException,
> as OP_INPROGRESS event tries to do STARTING -> STARTING transition.
> # However at task end we support INSTALLED -> STARTED transition for STARTED
> event. So tasks finish normally.
