7a2f508b50 Fix network info for docker containers running with --net=host. 
Docker still reports a loop device for these. Need to check for
more than one device to mark network as available.

a123fd72d8 Add logic to read custom metric config files from container root. 
Docker does not provide the rootfs path through docker inspect or statefile
and the path is dependent on the storage driver being used.

Instead of enumerating the storage drivers, we pick a pid from the container
and get the config from /proc/pid/root. Although a bit expensive, this method
works for non-docker containers too.

e43ada2e00 Add 'bytes available' to fs info. 
The current capacity and usage numbers are insufficient to figure out
actual bytes available for a non-root user for the fs. Available is the
value used by df and the one we need to track to detect low diskspace
condition.

4b4312b290 Improve approximation of container creation time. 
Containers with subcontainers always report creation time to be same as the time
of creation of the latest subcontainer.

Still not an ideal solution, but accurate for most practical purposes.

9ce178f707 Lazily init DBus only when it is needed 
OpenShift has some cAdvisor packages in its import chain. The init() here
invokes Dbus start even when cAdvisor is not actively running or being
used (in our packages).  This change makes the systemd check and dbus
initialization and connection lazy, occuring only the first time someone
invokes UseSystemd().

ffdb6f5c7d Start() exits gracefully when there are no factories. 
This allows us to handle the case where there are no factories as
happens when testing in a non-container environment. We will still serve
the machine information that is available.

a0a419614f Add /storage endpoint to 2.0 API. 
/storage returns {device, mountpoint, capacity, usage} for all filesystems.
In addition, it also detect and applies label for each filesystem - currently two - "root", "docker-images".

/storage/<label> returns info about the filesystem with specific label. eg. /storage/root returns info for root filesystem.

86238d0179 Allow partial success of GetStats(). 
This should make us more robust in the face of failure (at the cost of
making the failures less prominent). We allow GetStats() to return an
error and a partial result. We will process the result and report the
error.

Fixes #306.

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.
