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.

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.
