d2e11efba2 libcontainer: use real number of CPUs for usage 
As of the 4.7 kernel, the cpustats field returned from libcontainer
contains values for every possible cpu (including nonexistent ones).
The extra values are all 0s.

If we assume that hotplug events won't happen, we can get a more
accurage cpu count by using runtime.NumCPU and then ignoring any values
beyond that.

69c085d9fa Cache the Docker thin pool name 
Cache the Docker thin pool name in the dockerFactory and pass it to each Docker container handler,
instead of calling `docker info` each time a new container handler is created, as the thin pool name
is extremely unlikely to change.

Report container FS metrics into prometheus /metrics 
PerDiskStats reported from cgroups were not being surfaced into
prometheus. In order to properly correlate the metrics, we need to
assign a device label to each metric (which is the FS or device path).
Since blkio cgroup tracks devices, we create a synthetic device
`/dev/NAME` for the metric.

Assign a Device label to each PerDiskStat for the handlers up front, and
then surface the PerDiskStat values into the prometheus metrics. Report
two new metrics - total bytes read and total bytes written.

1653733ea7 Expose cpu cgroup CFS prometheus metrics 
If CPU quota is configured (cpu.cfs_quota != -1) the CFS will provide
stats about elapsed periods and throtting in cpu.stats. This change
makes these information available as container_cpu_cfs_* metrics.

2b525ff87e Ensure minimum kernel version for thin_ls 
Ensure that kernel >= 4.4.0 or RHEL/Centos 7 kernel >= 3.10.0-366 exists before starting the thin
pool watcher. Prior versions have a bug in which reserving and releasing the metadata snapshot can
cause thin pool corruption.

307d1b1cb3 Modify working set memory stats calculation 
Change working set calculation to usage - total_inactive_file, rather than
usage - total_inactive_anon - total_inactive_file. Since writes to tmpfs
get tracked as total_inactive_anon when swap is disabled, the old
calculation would under-report memory pressure.
