Add a new tool project to get non-crucible pods' metrics

[HughNhan]

There is a need to get non-crucible pod metrics such as the OVN pods' CPU and memory consumption.
Currently, we can identify 2 options:

1. Directly query prometheus to get the metrics
2. Use "kube-burner ocp index" to query

Could this be done with a "cgroup profiler" that is compatible with multiple environments (ie. k8s, Linux, etc.)?

This is essentially the equivalent of pidstat for pods/cgroups.
