Add information for Manager Addresses in the output of docker info

Browse Source 
As is specified in 28018, it would be useful to know the manager's addresses
even in a worker node. This is especially useful when there are many
worker nodes in a big cluster.

The information is available in `info.Swarm.RemoteManagers`.

This fix add the information of `Manager Addresses` to the output
of `docker info`, to explicitly show it.

A test has been added for this fix.

This fix fixes 28018.
