Add server show command

[briangustafson]

Proposed interface and output is below. A few notes:

• The output is taken directly from server create, see https://github.com/oracle/knife-bmcs/blob/master/lib/chef/knife/bmcs_server_create.rb#L160. We should probably share the code.
• The method of getting IP address in server create is simpler than the logic needed in the general case, since on server create we know that the instance can only have 1 VNIC and that that VNIC is in the same compartment.
• We can certainly improve on the output below in the future (for one, it would be nice to show the name of the compartment and the image in addition to the ID), but the output below should be a reasonable starting point. (It's also useful to look at what the console is showing for an instance.)
• "server show" is the standard terminology used in other knife plugins, as opposed to server get or info.

knife bmcs server show --instance-id

The code that displays the hostname, private ip address and public ip address is currently geared towards displaying those parameters from the first/primary vnic for a server instance. How do you want the information displayed for additional vnic interfaces?
