Add throttling parameter on az graph query

**Related command**

`az graph query`

**Is your feature request related to a problem? Please describe.**

Repeatedly getting throttled when using `az graph query` on large deployments. Have had the limits increased on my service principal, but still getting throttled. Relates to MS Enterprise support ticket #2407220030002618

**Describe the solution you'd like**

When using `az graph query` and a throttle limit is reached, slow down the CLI response until it is under the limit. Current behaviour is to hit the limit and return an error - we would prefer that the response was slowed down instead.

**Describe alternatives you've considered**

It would be hard to split out the principals, as many resources have cross-subscription permission dependencies (e.g. resource A in subscription 1 has permissions on resource B in subscription 2 which has permissions on resource C in subscription 3 etc.). Also, ultimately there would be the same net number of queries on the graph.
We've also considered implementing retry logic to look for a throttling error on CLI - messy!

**Additional context**

Affects our large deployments across many subscriptions. There are other resources in the Azure management plane (e.g. [setting SQL firewalls](https:/learn.microsoft.com/en-us/cli/azure/sql/server/firewall-rule?view=azure-cli-latest) ) that will just slow down the Azure CLI operations transparently to the user when some throttling limit is reached, and each CLI operation on this resource will just be slow until the throttling eases. We would expect `az graph query` to operate the same way (with an optional flag added to cancel the query instead of throttle), but instead it just errors out when the throttling limit is reached.
