Made changes to testUtilities to have a transport object which is used to identify enabled transports.

- In the future this transport object could hold additional transport
specific info
- Also re-did the transportNames property to be derived from the
transports property
- Lastly removed the transportEnabled function and replaced the
functionality with direct lookups in the transports property
#1455
Changed the syntax of [transport]Enabled to then utilize the transports property on testUtilities.
