- During concurrent operations in multihost environment,
it is possible that the implementer of `EndpointInfo`
is nil. It simply means the endpoint is no longer
available in the datastore.

Side effects:
- Decouple daemon and container to start containers.
- Decouple daemon and container to copy files.

- On `docker run --net <network id> ...`
the bug would cause the container to attempt
to connect to the network two times
- Also made sure endpoint creation rollback will
be executed on failures in `func (container *Container) connectToNetwork()`

This makes sure that these IPC mounts are cleaned up even when the
daemon is killed.

Since #15862, containers fail to start when started with --ipc=host if
/dev/mqueue is not present. This change causes docker to create
container-local mounts for --ipc=host containers as well as in the
default case.
