Make integration test local run friendlier

[data-sync-user]

Being able to run a large test suite against code running locally can be very useful while developing. The current Integration tests are very much designed to be run as a docker instance inside of our CI flow, and thus do not lend themselves well to running locally.

It would be useful to have:

• A document describing how to set up testing against a server running on localhost or somewhere in the local net.
• The ability to run against an existing, running server (which may be running a debugger)
• The ability to run an individual test from the integration suite.
• The ability to output test results to a log file with detailed input and output statements.

It’s preferred that the locally executed tester use the same tests as the CI integration tester to ensure that any new test introduced is available to both systems.
