feat: cilium integration support

[nimishamehta5]

Closes https://github.com/k8sgpt-ai/k8sgpt/issues/1238

📑 Description

Adds support for Cilium. Implements basic checks on usual Cilium daemonsets and deployments.

Ideally, we don't want to re-implement the huge number of checks Cilium already does, so I wanted to just read the cilium status -o jsonoutput if the user has Cilium CLI installed, and collect the errors from that report. But the errors are lost when reading the report JSON format. I filed a fix in cilium for that here: https://github.com/cilium/cilium/pull/34654 It is not reasonable to expect everyone to have the most updated version of the CLI even once this is released though, so we have to implement some checks ourselves.
