Sebastiaan van Stijn 8d43f5593a fix flag descriptions for content-trust
Commit ed13c3abfb242905ec012e8255dc6f26dcf122f6 added flags
for Docker Content Trust. Depending on the `verify` boolean,
the message is "Skip image verification", or "Skip image signing".
"Signing" is intended for `docker push` / `docker plugin push`.

During the migration to Cobra, this boolean got flipped for
`docker push` (9640e3a4514f96a890310757a09fd77a3c70e931),
causing `docker push` to show the incorrect flag description.

This patch changes the flags to use the correct description
for `docker push`, and `docker plugin push`.

To prevent this confusion in future, the boolean argument
is removed, and a `AddTrustSigningFlags()` function is added.

# push
```markdown
Usage: docker push [OPTIONS] NAME[:TAG]
Push an image or a repository to a registry
Options:
--disable-content-trust Skip image signing (default true)
--help Print usage
```
Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com)
registry or to a self-hosted one.
Refer to the [`docker tag`](tag.md) reference for more information about valid
image and tag names.
Killing the `docker push` process, for example by pressing `CTRL-c` while it is
running in a terminal, terminates the push operation.
Registry credentials are managed by [docker login](login.md).
## Concurrent uploads
By default the Docker daemon will push five layers of an image at a time.
If you are on a low bandwidth connection this may cause timeout issues and you may want to lower
this via the `--max-concurrent-uploads` daemon option. See the
[daemon documentation](dockerd.md) for more details.
## Examples
### Pushing a new image to a registry
First save the new image by finding the container ID (using [`docker ps`](ps.md))
and then committing it to a new image name. Note that only `a-z0-9-_.` are
allowed when naming images:
```bash
$ docker commit c16378f943fe rhel-httpd
```
Now, push the image to the registry using the image ID. In this example the
registry is on host named `registry-host` and listening on port `5000`. To do
this, tag the image with the host name or IP address, and the port of the
registry:
```bash
$ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
$ docker push registry-host:5000/myadmin/rhel-httpd
```
Check that this worked by running:
```bash
$ docker images
```
You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
listed.
