rpc/lib/client: jitter test updates and only to-be run on releases

Browse Source 
* Updated code with feedback from @melekes, @ebuchman and @silasdavis.
* Added Makefile clause `release` to only run the test on seeing tag
`release` during releases i.e
```shell
make release
```
which will run the comprehensive and long integration-ish tests.
