In [1], the "port list --long" command received a new column, showing
the trunk subports related to a parent port. The problem of this patch
is that the ``_formatters`` definition, that is shared with the "port
show" command too, is changed. The "trunk_details" information presented
in both commands differ:
* In the "port list" command, only the subports are presented, in order
to print a list of dictionaries without showing the ``trunk_id``.
* In the "port show" command, it is presented all the trunk information,
including the ``trunk_id``.
This patch includes functional tests to validate the fix.
