When logging per rank, we need good naming to make it easier to debug. Now provisioner.py::get_proc_mesh provides a mesh_name (#378), so i am just using it.

User can also pass a process name as input. Thats how we get the Controller name.

mlogger = await get_or_create_metric_logger(process_name="Controller")

The process_name then goes: LocalFetcherActor -> MetricCollector -> backend.init --> wandb.init(name)

get name here and pass it to

local_fetcher_actor = proc.spawn(
            "local_fetcher_actor", LocalFetcherActor, global_logger, process_name
        )

this function is called in provisioner.py, and thats how we get the process_name for every wandb run

logger = logging.getLogger(__name__)

in the near future the mesh might hold a name. When this happens, we can delete the function to use the call stack and just get it from the mesh. The rest of the PR stands.

Dumb q but what are we doing with this toy_rl stuff anyways? (Like is there some reason we're still keeping it around?)

a small thing but it's not immediately clear why we do this here vs get_proc_name_with_rank in other places. (after looking at the code i think it's a global vs local thing, but imo this could be more clearly documented)
