8a1280b2b6 metrics/cgroups: fix deadlock issue in Add during Collect 
The Collector.Collect will be the field ns'Collect's callback, which be
invoked periodically with internal lock. And Collector.Add also runs
with ns.Lock in Collector.Lock, which is easy to cause deadlock.

Goroutine X:

	ns.Collect
	  ns.Lock
	    Collector.Collect
	      Collector.RLock

Goroutine Y:

	Collector.Add
	  Collector.Lock
	    ns.Lock

We should use ns.Lock without Collector.Lock in Add.

Fix: #6772

Run go fmt with Go 1.17 
The new `go fmt` adds `//go:build` lines (https://golang.org/doc/go1.17#tools).

1239f54035 export cgroups collectors 
This makes it easier to extend the collectors to be used by external code and
task managers

8f870c233f support cgroup2 
* only shim v2 runc v2 ("io.containerd.runc.v2") is supported
* only PID metrics is implemented. Others should be implemented in separate PRs.
* lots of code duplication in v1 metrics and v2 metrics. Dedupe should be separate PR.
