Make `dvc pull --run-cache` allow `targets` for a granular pull process

[victormaricato]

Right now, if I do

dvc pull [target]
this will pull only the target I am interested in.

However, if I do dvc pull --run-cache [targets]
the target is ignored, everything is pulled from remote. Not even a warning is thrown that --run-cache does not accept granularly pulling files.

This is based on https://discuss.dvc.org/t/dvc-pull-run-cache-target/444 discussion

For the record: --run-cache flag is just a temporary solution and is not meant to accept targets. We will likely just support dvc pull target that will then somehow look into the run-cache by itself and pull by itself or suggest a hint on how to do it. run-cache is really an implementation detail that should be hidden away. We need to take a closer look at this.

Oh, ok. Is there any kind of estimative on this being prioritized?

As described in the forum, I was planning to use --run-cache as a workaround for deploying models, but the lack of targets selection makes it impossible.

Hi @maricatovictor ! Sorry for the delay. We've added this task to the next sprint (starting next week).
