cmd: add retry/backoff (#10069)

This commit adds retry/backoff to the registry client for pull requests.

Also, revert progress indication to match original client's until we can
"get it right."

Also, make WithTrace wrap existing traces instead of clobbering them.
This allows clients to compose traces.
