`--rm` is a client side flag which caused lots of problems:
1. if client lost connection to daemon, including client crash or be
killed, there's no way to clean garbage container.
2. if docker stop a `--rm` container, this container won't be
autoremoved.
3. if docker daemon restart, container is also left over.
4. bug: `docker run --rm busybox fakecmd` will exit without cleanup.
In a word, client side `--rm` flag isn't sufficient for garbage
collection. Move the `--rm` flag to daemon will be more reasonable.
What this commit do is:
1. implement a `--rm` on daemon side, adding one flag `AutoRemove` into
HostConfig.
2. Allow `run --rm -d`, no conflicting `--rm` and `-d` any more,
auto-remove can work on detach mode.
3. `docker restart` a `--rm` container will succeed, the container won't
be autoremoved.
This commit will help a lot for daemon to do garbage collection for
temporary containers.

This fix tries to address the issue raised in #23498 to allow unset
`--entrypoint` in `docker run` or `docker create`.
This fix checks the flag `--entrypoint` and, in case `--entrypoint=` (`""`)
is passed, unset the Entrypoint during the container run.
Additional integration tests have been created to cover changes in this fix.
This fix fixes#23498.

e.g.
```
$ docker run -i --restart always busybox sh
pwd
/
exit 11
<...hang...>
```
This is because Attach(daemon side) and Run(client side) both hangs on
WaitStop, if container is restarted too quickly, wait won't have chance
to get exit signal.

This fix tries to fix the discrepancy between API and CLI on hostname
validation. Previously, the hostname validation was handled at the
CLI interface in runconfig/opts/parse.go and return an error if the
hostname is invalid. However, if an end user use the remote API to
pass the hostname, the error will not be returned immediately.
Instead the error will only be thrown out when the container creation
fails. This creates behavior discrepancy between API and CLI.
In this fix, the hostname validation was moved to
verifyContainerSettings so the behavior will be the same for API and
CLI.
After the change, since CLI does not handle the hostname validation
any more, the previous unit tests about hostname validation on CLI
in runconfig/opts/parse_test.go has to be updated as well because
there is no validation at this stage. All those unit tests are moved
to integration test TestRunTooLongHostname so that the hostname
validation is still properly covered as before.
Note: Since the hostname validation moved to API, the error message
changes from `invalid hostname format for --hostname:` to
`invalid hostname format:` as well because `--hostname` is passed
to CLI only.
This fix fixes#21595.
