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.

This fix tries to address 27902 by adding a flag `--host`
to `docker service create` and `--host-add/--host-rm` to
`docker service update`, so that it is possible to
specify extra `host:ip` settings in `/etc/hosts`.
This fix adds `Hosts` in swarmkit's `ContainerSpec` so that it
is possible to specify extra hosts during service creation.
Related docs has been updated.
An integration test has been added.

This fix is a follow up to #27567 based on:
https://github.com/docker/docker/pull/27567#issuecomment-259295055
In #27567, `--dns-options` has been added to `service create/update`,
together with `--dns` and `--dns-search`. The `--dns-opt` was used
in `docker run`.
This fix add `--dns-option` (not `--dns-options`) to `docker run/create`, and hide
`--dns-opt`. It is still possible to use `--dns-opt` with
`docker run/create`, though it will not show up in help output.
This fix change `--dns-options`to --dns-option` for `docker service create`
and `docker service update`.
This fix also updates the docs and bash/zsh completion scripts.

This fix tries to address the proposal raised in 27921 and add
`--cpus` flag for `docker run/create`.
Basically, `--cpus` will allow user to specify a number (possibly partial)
about how many CPUs the container will use. For example, on a 2-CPU system
`--cpus 1.5` means the container will take 75% (1.5/2) of the CPU share.
This fix adds a `NanoCPUs` field to `HostConfig` since swarmkit alreay
have a concept of NanoCPUs for tasks. The `--cpus` flag will translate
the number into reused `NanoCPUs` to be consistent.
This fix adds integration tests to cover the changes.
Related docs (`docker run` and Remote APIs) have been updated.

When a container is attached to an "--attachable" network, it strictly
forms the attacherKey using either the network-id or network-name
because at the time of attachment, the daemon may not have the network
downloaded locally from the manager. Hence, when the NetworkDettach is
called, it should use either network-name or network-id. This fix
addresses the missing network-id based dettachment case.

Squashing does not destroy any images or layers, and preserves the

Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`

from each layer into a single new layer and references all the parent's
