Support listing network availability zones

Update the "os availability zone list" command to support listing
network availability zones along with the currently listed compute
and volume availability zones. This adds the --network option to
the command in order to only list network availability zones. By
default, all availability zones are listed. The --long option
was also updated to include a "Zone Resource" column which is
applicable to network availability zones. Example zone resources
include "network" and "router".

If the Network API does not support listing availability zones
then a warning message will be issued when the --network option
is specified.

This support requires an updated release of the SDK in order
to pull in [1].
