e3ab15417c Ignore update errors for dead containers. 
This adds an Exists() interface to detect when the container is dead.
Before reporting an update error we check is Exists() is true.

Some documentation was added as well.

c005bc1722 Merge pull request #326 from vmarmol/integration

fa00344601 Register inotify watches on all cgroup hierarchies. 
We used to only register them on the first hierarchy that was created (I
think this was unintentional). This caused some weird edgecases where
we'd try to delete a watch event we didn't create. It is an error we
ignore today (since we fix it in < 60s) but delays our destruction of
the container.

0e603d2709 Let the raw driver handle the /docker container. 
This will give us stats on this container and since the /docker UI
endpoint, it no longer serves the purpose it once did.

fc622a4b56 Fix raw driver's setting of CPU mask. 
We used to include it with the trailing "\n" which gave us parsing
errors in the UI (and the reason why they didn't show up in any of those
containers).

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).

b8ed0bd0e3 Mounted partitions space usage metrics per container 
This computes the space usage for mounted partitions. It takes in a list of mounted partitions from containerHints
and computes the device's disk usage(so each mount must be a separate partition). This is useful for users who
mount partitions on containers and store most of the container's persistent data on those partitions.
