Improve query params in uri KeyValue with HTTP interface client 

Prior to this commit, the HTTP interface client would create URI
templates and name query params like so:
"?{queryParam0}={queryParam0[0]}".
While technically correct, the URI template is further used in
observations as a KeyValue. This means that several service methods
could result in having the exact same URI template even if they produce
a different set of query params.

This commit improves the naming of query params in the generated URI
templates for better observability integration.

Closes gh-34176
