client.ImagePush(): default to ":latest" instead of "all tags"
The `docker push` command up until docker v0.9.1 always pushed all tags of a given
image, so `docker push foo/bar` would push (e.g.) all of `foo/bar:latest`, `foo:/bar:v1`,
and `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see issue 3411 and PR 4948 (commit e648a186d68dcb3ee0d6123b041c5aa66438cc89).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image".
`docker pull` had a similar behavior, but PR 7759 (9c08364a412a51c80e8d17ae14f92549dc543e68)
changed the behavior to default to the `:latest` tag, and added a `--all-tags` flag
to the CLI to optionally pull all images.
This patch implements the API client changes to make `docker push` match the behavior
of `docker pull`, and default to pull a single image, unless the `all` option is passed.
