e5b6bfa94f add whitelisted env as container metadata 
This add Envs to container spec as a metadata source. When using prometheus
exposition format, they will be merged into the list of metrics' labels.

Also changed the cli flag to docker_env_metadata_whitelist, and add refenrences
of whitelist envs to API

4965f069b7 Fix case statements dealing with storageDriver 
cf0adcc817 introduced two switch
statements to facilitate the addition of the `overlayStorageDriver`;
unfortunately neither of them conform to the Go switch semantic, which
does not fallthrough unless explicitly requested. In one case this was
innocuous (because a `break` was effectively the same as a no-op) but in
the other it would cause the `HasFilesystem` bool to not be set
appropriately in the case of `aufsStorageDriver` being used.

IMHO it's also more idiomatic to perform the default behaviour in the
default case rather than pre-setting and overriding it.

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.

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.

This adds an Exists() interface to detect when the container is dead.

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.
