service framework - metadata options

[aricart]

Overview

Micro ADR-32 now allows optional metadata to be specified on the the service and on endpoints. The metadata is simply Record<string,string>. Note that schema report also includes any metadata associated with the endpoint.

The cross-client test has been updated (on the dev branch) if you are using it, it will flag if metadata is not specified in your test service.
