e5200948f5 Add a disk map to machine info. 
This is read once at start of cAdvisor. We can use this to report
machine state as well as return logical name for block devices in UI.

181e12dda2 Refactoring and fixes of /docker API endpoint. 
This canges the output of the Docker endpoint to be a map so that it is
more consistent from single to multiple returns. It also refactors
internally how we handle both types of requests.

Without this PR the /docker API endpoint is broken completely so this
change in format has no effect anyways.

These changes are tested by the upcoming integration tests.

742bb8c724 Do not duplicate Docker container output. 
Since Docker containers are known by more than one name we were
returning them once for every name they're known by. This change makes
the returned containers unique.

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.

cb80366c6d Fix logic for deciding if Docker container was not found.

b63d61ca97 Use inotify to watch for new containers. 
This reduces cAdvisor CPU usage below 1% in my CoreOS system.

We also reduce global housekeeping to every 60s as a fallback in case we
miss an event.

41e27e40ef Adding v1.1 remote API. 
Main addition is the "subcontainers" resource which provides
ContainerInfo for all subcontainers (recursively and including
self) of the specified container.

1edb798de5 Features: 
Added Network Stats to Container Info. It still not exposed via the HTTP UI.
Bug fixes:
1. Modified docker handler to use libcontainer.GetStats instead of quering the fs package.
2. cAdvisor will not stall if any of its core operations fail.
3. cAdvisor will safely ignore any inactive or leaked docker containers. When containers are leaked cgroup state exists but docker is not aware of them.
