[design discussion] azure-core support for optional path parameter

TCGC output

          kind: http
          path: /optional{name}
          uriTemplate: /optional{/name}
          verb: get

The current RestProxy annotations cannot support such. Whichever template it takes (/optional{name} or /optional/{name} or even /optional{/name}), it likely has to adjust the slash leading / based on whether the path parameter is null or non-null.

Thanks for raising this issue @weidongxu-microsoft, will take a further look into what's going on here.

FYI @samvaity to see if this same issue occurs in annotation processing

Key vault service is doing this in their PR Azure/azure-rest-api-specs#34032, but not yet merged

Their latest api-version is 7.6, and it currently does not have this optional path.
