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.

4e028d7995 Make housekeeping interval dynamic, fist signal is resource usage. 
If no resources are used by the container since the last housekeeping,
we double the housekeeping interval until --max_housekeeping_interval.
If usage was detected, we drop it back to the baseline
(--housekeeping_interval).

From my tests this reduces CPU usage in CoreOS from ~8% to ~3% with no
real loss of accuracy.

Fixes #159

1bdef9797b Prepare housekeeping interval to be dynamic. 
Change housekeeping to be from a fixed interval to a possibly varied
interval decided by nextHousekeeping().

1a24eed18f Fix storage driver buffer duration default value. 
The cache will now hold atlest the minimum number of stats required by the UI and more
if the buffer duration is longer than the default.

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.

ef13440034 Addressed comments. Another series of bug fixes. 
Modified the docker driver and lmctfy driver to skip containers they cannot handle.

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.

1636c3e759 Change ContainerHandlerFactories to decide what containers they support. 
This allows a ContainerHandlerFactory to register a CanHandle() function
which is called to determine whether the factory can handle a particular
container.

This commit disables being able to run cAdvisor without lmctfy. This
should be enabled again with a "no-op" global factory which I would like
to do in a separate PR.
