Not sure what you mean. The patch currently allows container executor config
keys for all the types. I should have mentioned this before – it didn't seem
worthwhile to only add "shared" when there are so many other modes, so I have
been working towards supporting any single mode. I am thinking now that I could
use a regex like [rw|ro|z|Z|s|[r]shared|[r]slave|[r]private|nocopy] to check
the mode, but would prefer not to add support for comma separated modes in this
ticket – we could open a separate ticket for that.

I think rslave,rprivate are propagation options, and they are not specific
mode. With this change, if we want to white list a rw mount with slave option,
how do we specify in container-executor.cfg?
docker.allowed.rw,slave-mounts seems to be the key that container-executor
expected to check. I am not sure if this is desired config syntax from user
point of view. We probably want to classify the propagation options to
docker.allow.rw-mounts.
