The option `--no-default-ipam` is replaced with
`--no-default-ipalloc`; the former will still work (in a 'last one
wins' way), but its usage message says it's deprecated.
Tells the proxy not to do anything with this container. We set it when
running weaveexec/weave/etc containers, so that the weave script works
through the proxy.
Pass `-e WEAVE_CIDR=` to your container to use IPAM. If IPAM is not
enabled on the weave router, the container will be booted without weave
networking.
I'm not crazy about adding *another* undocumented weave cli command
(ipam-cidr), but it saves the proxy messing around finding container
IPs.
