Worker Pool implementation to limit amount of requests happening in parallel

[freakytoad1]

Since Go is pretty good at concurrency and API calls are relatively slow, it makes sense to do concurrent calls to a PAN device to get more information in a shorter amount of time. Though through testing a looking at pan docs terraform recommendations, the highest the concurrent calls should get is around 5.

My Request: accept an input when making a new Client in PanGo that limits the number of concurrent calls to the amount requested. And maybe default to 5 if not requested. In my scripts that use PanGo I've been using a Worker Pool implementation to achieve this but would love if this was built-in to the client already. Would save a lot of repeated code. Really nice explanation here
