8f0f2299ab Make network fields signed integers. 
The kernel reports -1 in case of errors so it should be an allowable
returned value.

Fixes #454.

aa398c800a Add scheduler type to disk info. 
Type can be one of "none", "noop", "deadline", "cfq".
For block devices that don't use scheduler (like dm), the type will be "none".
We'll also report "none" for partitions when we start reporting those.

cbdd96a554 Add task load stats to containers. 
The stats are only populated when cAdvisor is running outside network namespaces.
We'll add a different backend to retrieve the same data from within namespaces.

machine state as well as return logical name for block devices in UI.

They may be zero. Also removed Limit from MemoryStats, that belongs in
MemorySpec and is there today. All info requests return the spec.

f97e57df88 Simplify how the Docker containers are handled. 
This is done by introducting the concept of "namespaces" of container
names. The aliases of a container are under this namespace. Namespace
names are of the form:

//<namespace>/<alias>

This allows us to (within cAdvisor) query all docker containers as
//docker regardless of whether this is a systemd or a non-systemd system.

This does break our ability to handle Docker aliases with the /container
endpoint. I think this is acceptable as our support there was not
consistent between system types.

e9d6289964 Added /proc/diskstats 
Read disk io information from /proc/diskstats.
This will allow the user who provides partition container hints to get partition-specific io (blkio provides io for the container, but at the disk device level).

b9e70f0240 Filesystem stats are now per container. As of now, fs stats are reported only for the

To make cadvisor detect all the disks, the rootfs of host needs to mounted

4e028d7995 Make housekeeping interval dynamic, fist signal is resource usage. 
If no resources are used by the container since the last housekeeping,
we double the housekeeping interval until --max_housekeeping_interval.
If usage was detected, we drop it back to the baseline
(--housekeeping_interval).

From my tests this reduces CPU usage in CoreOS from ~8% to ~3% with no
real loss of accuracy.

Fixes #159
