Add support for AlloyDB system stats

[rcmaniac25]

Recently I setup some collectors for AlloyDB deployments and found that system stats weren't collected. What would it take to collect said information? Not sure what, if any, other information is needed.

Good question - we currently don't collect system statistics for Cloud SQL and AlloyDB, mostly since it'd require asking for additional permissions, and adding the relevant code here.

That said, I'll bring this up in an internal planning session and see if we can prioritize it soon. We recently added support for collecting system statistics on Azure, so adding them for GCP would complete the major providers.

Given that adding log insights for AlloyDB requires extra permissions, I think it should be fine.

👍 CloudSQL metrics would be useful for us
