Just a small grammatical correction, but it is unnecessary to repeat "to," after the colon, and deleting it makes the format of the list more consistent and readable.

Container state counts are used for reporting in the `/info` endpoint.
Currently when `/info` is called, each container is iterated over and
the containers 'StateString()' is called. This is not very efficient
with lots of containers, and is also racey since `StateString()` is not
using a mutex and the mutex is not otherwise locked.
We could just lock the container mutex, but this is proven to be
problematic since there are frequent deadlock scenarios and we should
always have the `/info` endpoint available since this endpoint is used
to get general information about the docker host.
Really, these metrics on `/info` should be deprecated. But until then,
we can just keep a running tally in memory for each of the reported
states.

This makes sure that multiple users of MountPoint pointer can
mount/unmount without affecting each other.
Before this PR, if you run a container (stay running), then do `docker
cp`, when the `docker cp` is done the MountPoint is mutated such that
when the container stops the volume driver will not get an Unmount
request. Effectively there would be two mounts with only one unmount.

if docker exec exit and at the same the the container is pause,
there could be a chance the `docker exec exit` will fail
```
$ docker exec -ti 388c7f47a06c sh
/ # exit
Error response from daemon: Container 388c7f47a06cce0856266ffd56a2ce2901689ca7a6b9cd741b37652418448f2b is paused, unpause the container before exec
```
To reproduce this error easilly, we can add a sleep in `containerPause`

Remove unused arguments to commit.
This will allow us to remove all the runConfig mutate+revert code that
is scattered around builder dispatchers/internals

When there is an error unmounting a local volume, it is still possible
to call `Remove()` on the volume causing removal of the mounted
resources which is generally not desirable.
This ensures that resources are unmounted before attempting removal.

Don't error if no group is specified, as this was the prior API. Also
don't return a docker specific error message as this is in `/pkg` and
used by other projects. Just set the default group for the current
user/group consuming the package.

This fixes issues where the underlying filesystem may be disconnected and
attempting to unmount may cause a hang.
