Usually, the error message of multi delete is:
"'result' of 'total' 'objects' failed to delete"
the objects is a plural form.
To match the other multi delete error messages
in OSC, change the object in delete error message
in networkv2 to a plural form. Just add a 's' in
the message.

Use file logger for all command specific logs.

This patch also fixes some usage that doesn't
follow rules in:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html

After this patch, all self.log and self.app.log
will be standardized to LOG().

NOTE: In shell.py, we got the log in class OpenStackShell,
      which is also known as self.app.log in other classes.
      This logger is used to record non-command-specific logs.
      So we leave it as-is.

This patch rework "network delete" command following the
rules in doc/source/command-errors.rst.

In "network delete" command, there are multiple REST API
calls, and we should make as many of them as possible.
And log error for each one, give a better error message.
Also return a non-zero exit code.

Partial-Bug: #1556719

This patch set introduces the NetworkAndComputeLister and
NetworkAndComputeShowOne classes which are related to the
NetworkAndComputeCommand class.  These classes are for commands
that must support neutron and nova network.  The new classes
allows both the parser and actions to be unique.

Refactored the 'os security group rule delete' command to use the
SDK when neutron is enabled, but continue to use the nova client
when nova network is enabled.

This patch set also introduces new FakeSecurityGroupRule classes
for testing network and compute security group rules. And fixes
were made to the network FakeSecurityGroup class.

Refactored the 'os security group delete' command to use the SDK
when neutron is enabled, but continue to use the nova client when
nova network is enabled.

This patch set introduces a new NetworkAndComputeCommand class
to be used for commands that must support neutron and nova network.
The new class allows both the parser and actions to be unique.
The current DeleteSecurityGroup class is now a subclass of this
new class and has moved under the network v2 commands.

This patch set also introduces a new FakeSecurityGroup class for
testing security groups.

And finally, this patch set updates the command documentation
for security group and security group rule to indicate that
Network v2 is also used.
