dev: Add system metrics collection and UI

[javierhonduco]

Would like to have some basic system metrics such as CPU, memory usage, etc to our Minikube cluster during testing as I think it would be useful to find issues during development.

Some metrics I would like to have:

• CPU and memory usage per process (broken down by private, shared, and anonymous)
• Memory / IO / CPU pressure (PSI metrics) per process
• Opened file descriptors
• Threads for each process and metrics for them
• (feel free to add more)

Perhaps we could use something like Grafana?

We already have most of these metrics using the Go runtime collector, node_exporter, etc. So we just need to provide facilities for the local development environment.

And we usually use Grafana dashboards (internally Polar Signals). For the last bit, we also have this issue https://github.com/parca-dev/parca-agent/issues/646.

As we already have this internally, I'll close this issue

No, need to close it. Let's talk offline.

Let's provide a monitoring mixin for Parca (for more context https://monitoring.mixins.dev) And add kube-prometheus to the local testing setup. Similar to https://github.com/parca-dev/parca-demo/tree/main/kube-prometheus
