Show connected containers in network view

[stuartthomson]

I would like to be able to see which containers are connected to a docker network. This would allow me to quickly see that for example my docker-compose file created the network I imagined it would and correctly attached the containers. It also would allow me to quickly know which containers I should be able to see when inside an interactive prompt of a container. Preferably I would also be able to use this view to interact with the containers including disconnecting them from the network.

I often find myself having to do a docker network inspect NETWORK_NAME to find this information, and would prefer to always have it visible.

@stuartthomson meanwhile, you might find https://github.com/portainer/portainer/ useful.

@stuartthomson the settings stuff is merged in master. You're welcome to take a stab at adding containers, but take a look at the "Group By" setting for both the containers view and networks view first (There should be a gear icon for each view). I'm curious if we could group containers by network in the containers view which sounds simpler than adding containers to the networks view.

As an aside, feel free to take a look at the settings for the network view and add any more you think are useful or let me know if you think we should change the defaults

@EricJizbaMSFT I'll take a look at this, thanks for the heads up!

Related to #2592, so I'll put this into 1.10.0 milestone.
