Working towards connection string support in service bus
Connection settings class fully plumbed through config
Switched tests to running off connection string instead of individual env. variables
Fixed up exception reporting, fixed so tests actually use connection strings.
Adding testing for various configuration permutations.
Made connection settings package visible rather than public.
Added test of settings wrap uri via connection string.
Only replace sb:// at start of connection string value
