Working directory processing was handled differently for Hyper-V and Windows-Server containers, as annotated in the builder documentation (updated in this PR). For Hyper-V containers, the working directory set by WORKDIR was not created. This PR makes Hyper-V containers work the same as Windows Server containers (and the same as Linux).
Example (only applies to Hyper-V containers, so not reproducible under CI environment)
Dockerfile:
FROM microsoft/nanoserver
WORKDIR c:\installer
ENV GOROOT=c:\installer
ADD go.exe .
RUN go --help
Running on Windows Server 2016, using docker master without this change, but with daemon set to --exec-opt isolation=hyperv as it would be for Client operating systems.

Now compare the same results after this PR. Again, first with no explicit isolation (defaulting to Hyper-V containers as that's what the daemon it set to) - note it now succeeds 😄

clean remove object files
doc show documentation for package or symbol
env print Go environment information
fix run go tool fix on packages
fmt run gofmt on package sources
generate generate Go files by processing source
get download and install packages and dependencies
install compile and install packages and dependencies
list list packages
run compile and run Go program
test test packages
tool run specified go tool
version print Go version
vet run go tool vet on packages

And the same with forcing process isolation. Also works 😄

Fixes#22564
When an error occurs on mount, there should not be any call later to
unmount. This can throw off refcounting in the underlying driver
unexpectedly.
Consider these two cases:
```
$ docker run -v foo:/bar busybox true
```
```
$ docker run -v foo:/bar -w /foo busybox true
```
In the first case, if mounting `foo` fails, the volume driver will not
get a call to unmount (this is the incorrect behavior).
In the second case, the volume driver will not get a call to unmount
(correct behavior).
This occurs because in the first case, `/bar` does not exist in the
container, and as such there is no call to `volume.Mount()` during the
`create` phase. It will error out during the `start` phase.
In the second case `/bar` is created before dealing with the volume
because of the `-w`. Because of this, when the volume is being setup
docker will try to copy the image path contents in the volume, in which
case it will attempt to mount the volume and fail. This happens during
the `create` phase. This makes it so the container will not be created
(or at least fully created) and the user gets the error on `create`
instead of `start`. The error handling is different in these two phases.
Changed to only send `unmount` if the volume is mounted.
While investigating the cause of the reported issue I found some odd
behavior in unmount calls so I've cleaned those up a bit here as well.

"VolumeDriver.Mount" is being called on container start.
Make the symmetric call on container stop.

"--restart" and "--rm" are conflict options, if a container is started
with AutoRemove flag, we should forbid the update action for its Restart
Policy.
