Tianon Gravi d99e8d2c3b Unhide containerd-namespace flags
The daemon expects to manage/handle everything going into the containerd namespace it uses, and things break when it shares that namespace with a second instance, so we should expose these flags and expect users that want two daemons sharing a containerd instance to use separate namespaces for them.
