Is there a way to inspect the number of executors a job is running with (within the job itself)?

`OpExecutionContext.run_config` allows us to inspect the run configurations, and I'm able to inspect `max_concurrent` in there, but _only_ if it's provided as a value when launching the job via Dagit.

based on <https://docs.dagster.io/_apidocs/execution#dagster.multi_or_in_process_executor|this>:
```The max_concurrent arg is optional and tells the execution engine how many processes may run concurrently. By default, or if you set max_concurrent to be 0, this is the return value of python:multiprocessing.cpu_count().```
so, i can inspect the `OpExecutionContext.run_config`, get the `execution.config.max_concurrent` key.

if it's 0 or doesn't exist as a key in the `run_config`, then i should just use the `multiprocessing.cpu_count()` value?

is there a built-in alternative?

There is no built-in alternative, but this is something I think we should add to the `OpExecutionContext`. Would you mind opening a GH issue?
