Missing formatter for port property: trunk_details

[Bence Romsics]

This is a follow-up to bug #1672724:

https://bugs.launchpad.net/python-openstacksdk/+bug/1672724

That is: openstackclient did not display the 'trunk_details' port attribute (originally introduced in newton for trunk parent ports). The root cause of the problem was that openstacksdk did not know about the new attribute. Now that is fixed in https://review.openstack.org/445501, so openstackclient will get the 'trunk_details' attribute. The trunk_details attribute has a complex structure, which at the moment is dumped as json in the cli. openstackclient should have a formatter to pretty print it.

A patch is on the way to gerrit.

Hi Bence:

I'm tracing the whole column content format BP[1], the compute part commands had been completed and ready for review[2], I want to collect some feedback from other reviewers, then start to volume/network commands. I think the bug should be a part of that BP, I would like to fix it by the way, of course, if you have time to help contributing the network commands, it would be nice.
