longer needed.

Remove a useless arg in range()

Modify tests/test_v3_auth.py, remove the useless arg ("start index" = 0)
since its default value is 0. There was no range(0, N) being called in
any other place except here in keystone sources.

Fixes: Bug #1215482
Clean up keystone-manage man page

Several warnings were generated from keystone-manage when
building docs. Also, the options without a description
didn't display correctly in the rendered result.

Also, I added a description for the new db_version subcommand.

To generate the new option list, I ran keystone-manage --help
and copy-pasted the options into the doc.

remove flake8 option from run_tests.sh

flake8 will read the section [flake8] of tox.ini to guide the
behavior. In run_tests.sh, the function run_flake8() does not
need the falke8 option any more.
