Send push-style event only if EventService enabled

As per DMTF Redfish, if the event service is disabled, events are not
expected to be posted to the existing subscribers

This commit adds validation to check "ServiceEnabled" property while
sending events. An additional check is made not to attempt sending
events if there are no event subscribers at BMC

Tested by:
Using DMTF Redfish-Event-Listener script with some local modification
to support the latest event subscription specifications

 1. With a Push-style event subscriber setup, set "ServiceEnabled" to
    false
    PATCH /redfish/v1/EventService -d '{"ServiceEnabled":false}'
 2. Generate events and check no events are posted to subscriber
 2. Set "ServiceEnabled" to true. BMC should resume sending further
    events
 3. Check if BMC attempts to send events by forming the eventRecords
    when there are no subscriptions made - Verified with traces that
    events are not sent out
 4. With "ServiceEnabled" set to false, verified the SubmitTestEvent
    fails
