What type of PR is this?

What this PR does / why we need it:

In our e2e tests, controller logs for CAPZ, CAPI, ASO, etc. stop being collected after the first test completes for some unknown reason. Here I'm pulling ideas from kubernetes-sigs/cluster-api#4706 and kubernetes-sigs/cluster-api#7935 to see if those improve the situation for CAPZ.
