Default PathType match should be prefix

[robscott]

The current default behavior for PathType matching is / + Exact. I think it would be preferable to default to Prefix as the path type matching so by default a rule matches all requests. This would make it easier to initially set up a Gateway + Route combination that routed requests to all paths to a Service. I believe this would also more closely match user expectations when interacting with this API.

Yep, I agree that exactly matching / is a pretty unintuitive default :)

Ignore this - just testing:
