Io.rancher.container.ip Docker label not set on 1.5.9

Hi Everyone,

My apologies if this is a known issue but I had a scour of the open issues and came up blank.

We have noticed that when running docker 17.03.0-ce the io.rancher.container.ip label is not set on containers.

This missing label is preventing our monitoring tools from discovering the IP to use when talking to newly started containers.

Was this label/functionality removed or is there a known bug?

Many thanks!
Luke W
