1. What is the problem?
When writing the manual installation guide, I find that configuration
file generator fails to execute because there is an module import error
in opts.py for local and central plugin configuration. Actually there's
no need to generate configuration sample for plugin since the original
Neutron configuration file will be used, this is left without clearing
during the Tricircle splitting.
2. What is the solution to the problem?
Remove the entry for generating plugin configuration sample in tox.ini.
Also, tox.ini is modified to only install neutron dependency for py27
test, which will speed up pep8, docs and genconfig processes.
3. What the features need to be implemented to the Tricircle to realize
No new features
