Consolidate the supervisor's timeout settings into a single struct
- This struct represents the configuration of all timeouts. These timeouts are all interrelated to declare them all in one place. This should also make it easier to allow the user to override our defaults if we would like to implement such a feature in the future. Signed-off-by: Margo Crawford <margaretc@vmware.com>
