Reset the time increment if the container's execution time is greater
than 10s or else as a container runs and is restarted the time will grow
overtime.

We need to do this so that when a user asks docker to stop the container
and it is currently in the restart loop we don't want to have to wait
for the duration of the restart time increment before ack. the stop.

- Use a common struct for Volumes
- Split out some functionality in intializeVolume into separate functions
- Removes some duplicate code
- In general much easier to grok the code now

This PR moves the userland proxies for TCP and UDP traffic out of the
main docker daemon's process ( from goroutines per proxy ) to be a
separate reexec of the docker binary. This reduces the cpu and memory
needed by the daemon and if the proxy processes crash for some reason
the daemon is unaffected. This also displays in the standard process
tree so that a user can clearly see if there is a userland proxy that is
bound to a certain ip and port.

This also helps us to cleanly cleanup the proxy processes by stopping
these commands instead of trying to terminate a goroutine.

This changes the way the exec drivers work by not specifing a -driver
flag on reexec. For each of the exec drivers they register their own
functions that will be matched aginst the argv 0 on exec and called if
they match.
This also allows any functionality to be added to docker so that the
binary can be reexec'd and any type of function can be called. I moved
the flag parsing on docker exec to the specific initializers so that the
implementations do not bleed into one another. This also allows for
more flexability within reexec initializers to specify their own flags
and options.

`rm -f` was originally deprecated in favor of `rm --stop/--kill` since `rm
-f` was sending SIGTERM and potentially very slow.
Instead this will bring back `rm -f` but use SIGKILL isntead
