289e560efd replace golang.org/x/exp/inotify with standalone library 
context: kubernetes/kubernetes#68478

The inotify code was removed from golang.org/x/exp several years ago. Therefore
importing it from that path prevents downstream consumers from using any module
that makes use of more recent features of golang.org/x/exp.

Given that this code is by definition frozen and that the long term path should
be to migrate to fsnotify, replacing the current code by an identical standalone
copy doesn't have maintenance cost, and will unlock other activities for
kubernetes for example.

95f9c8c86f oomparser: update to use kmsg based parser 
This provides much more robust support for kernel logs via accessing the
`/dev/kmsg` interface to them directly.

3190c1c53d Fix journalctl leak 
This fixes the journalctl leak that occurs when a process that uses
cadvisor exits. See issues #1725 and
https://github.com/kubernetes/kubernetes/issues/34965.

fe722c7b02 oomparser: don't get stuck for certain processes 
The oomparser logic would end up stuck, unable to detect the end of a
given oom trace, for any process with a name that didn't match \w+.

This includes processes like 'python3.4' due to the '.', or
'docker-containerd' due to the '-'.

This fix was included in pr #1544 last year, but since that PR seems
dead it seems like a good idea to break this more important fix out.

I've updated the tests such that they would have caught this issue.

2f0af7bb40 Fixes for log tailing 
IN_ATTRIB inotify events are generated when atime / mtime is changed,
which would cause the tail to be reset, and reread the same log
again (generating duplicate events). Instead, watch the directory for
file delete / move.

Also, use an exponential backoff when retrying opening the file.

2e1f0e2a08 Use a dedicated CpuLoadReader per container 
This ensures each goroutine is given its own Netlink connection, and
presumably avoids having a message destined for one goroutine read by
another goroutine.

ee8701aa97 Netlink: aggressively close cgroup fds 
Not closing the FDs manually means we have to rely on garbage collection
to run before cgroup FDs are closed. If the system is running a lot of
load probes at a high-frequency (i.e. dynamic housekeeping isn't backing
off because of load variations), we can end up hitting our FD limit due
to keeping around lots of (useless) FDs.

b52cf9f5db cloudinfo: bugfix openstack identified as aws 
Because openstack and aws uses the exact same api,
the previous method to check for if running on aws
would have returned true on openstack as well.
