add property to configure rate limit

[david-alpert-nl]

We are using this provider to try populating a new Stack with ~35 global fields and content types.

When we run terraform plan and the provider tries to refresh state or apply we are running into many 429 (too many request) responses from the ContentStack Management API.

We would like a method to tune the number of API requests per second to match our ContentStack API Rate Limit and avoid going over.

Hi @david-alpert-nl thanks for reaching out!

This would indeed be useful. We could probably implement a rate limiter on the RoundTripper by adding something like https://pkg.go.dev/golang.org/x/time/rate to this.

I will put this on the backlog to look into, but due to priorities it might take a while. Feel free to send me a PR to add this if you need it quickly!
