[python-fuelclient] Executing 'fuel2 tag show' command leads to error

[Vitalii Kulanov]

 Detailed bug description:
If we try to execute 'fuel2 tag show' command the result will be:
[root@fuel ~]# fuel2 tag show
Traceback (most recent call last):
  File "/usr/bin/fuel2", line 10, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/fuelclient/main.py", line 81, in main
    return fuelclient_app.run(argv)
  File "/usr/lib/python2.7/site-packages/fuelclient/main.py", line 71, in run
    return super(FuelClient, self).run(argv)
  File "/usr/lib/python2.7/site-packages/cliff/app.py", line 226, in run
    result = self.run_subcommand(remainder)
  File "/usr/lib/python2.7/site-packages/cliff/app.py", line 309, in run_subcommand
    subcommand = self.command_manager.find_command(argv)
  File "/usr/lib/python2.7/site-packages/cliff/commandmanager.py", line 75, in find_command
    cmd_factory = cmd_ep.resolve()
  File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2365, in resolve
    raise ImportError(str(exc))
ImportError: 'module' object has no attribute 'TagShow'
But if we check 'tag' command list, 'tag show' command exists:
[root@fuel ~]# fuel2 tag
fuel2: 'tag' is not a fuel2 command. See 'fuel2 --help'.
Did you mean one of these?
  tag create
  tag delete
  tag download
  tag list
  tag show
  tag update

Steps to reproduce:
1. Deploy Fuel
2. Try to execute 'fuel2 tag show' command

Expected results:
Help message that shows existing tag commands, except 'tag show' one.

Actual result:
[root@fuel ~]# fuel2 tag show
Traceback (most recent call last):
  File "/usr/bin/fuel2", line 10, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/fuelclient/main.py", line 81, in main
    return fuelclient_app.run(argv)
  File "/usr/lib/python2.7/site-packages/fuelclient/main.py", line 71, in run
    return super(FuelClient, self).run(argv)
  File "/usr/lib/python2.7/site-packages/cliff/app.py", line 226, in run
    result = self.run_subcommand(remainder)
  File "/usr/lib/python2.7/site-packages/cliff/app.py", line 309, in run_subcommand
    subcommand = self.command_manager.find_command(argv)
  File "/usr/lib/python2.7/site-packages/cliff/commandmanager.py", line 75, in find_command
    cmd_factory = cmd_ep.resolve()
  File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2365, in resolve
    raise ImportError(str(exc))

Reproducibility:
Always

Description of the environment:
[root@fuel ~]# shotgun2 short-report
cat /etc/fuel_build_id:
 1083
cat /etc/fuel_build_number:
 1083
cat /etc/fuel_release:
 10.0
cat /etc/fuel_openstack_version:
 newton-10.0

Additional information:
Actually the problem is that 'fuel2 tag show' command doesn't exist and there is an erroneously added entry point for this command in setup.cfg file (https://github.com/openstack/python-fuelclient/blob/stable/newton/setup.cfg#L121)
Also note that this bug was fixed for master branch https://review.openstack.org/#/c/403665/, but still present in stable/newton and stable/mitaka

@Stas, what was a reason for Medium priority?

[Dmitry Pyzhov (dpyzhov)]

@Nastya, because there are other commands for tags management. This command is not that valuable.
