HTTP analyzer should have an in-cluster option

[adamancini]

Describe the rationale for the suggested feature.

Writing a quick supportbundle/preflight collector for in-cluster, and noticing that the http collector only has a host-analyzer.

Should probably have an in-cluster mode so we don't have to write regex to parse the results file.

Additional context

this would be an excellent addition!

+1 because the docs say The http collector can be used to execute http requests from inside the cluster. which is misleading.
