Adds new redfish unit testing for serviceroot

This type of testing can validate bmcwebs generated redfish. The ability
to validate the output of bmcweb is extremely useful because it will
guarantee correctness in certain cases.

This is an example of redfish unit testing. The long term goal is to
apply this type of testing to several other redfish responses.

To make this change many previous changes were needed
* Break serviceroot callback into the free function.
* Change ownership of the request and response objects.
* Change setCompleteRequestHandler logic
