Once we add debug testenv, we can use "tox -e debug" to debug test cases
when tox is running. Then tox will use oslotest which really debug our
test cases.

Only we should do is insert pdb into code.It's easy to use.

The same in trove:

To solve the problem of "db type could
not be determined" on py34 we have to run first the py34 env to, then,
run py27. This patch puts py34 first on the tox.ini list of envs to
avoid this problem to happen.

"Python 3.3 support is being dropped since OpenStack Liberty."
written in following URL.
https://wiki.openstack.org/wiki/Python3

And already the infra team and the oslo team are dropping py33
support from their projects.

Since we rely on oslo for a lot of our work, and depend on infra
for our CI, we should drop py33 support too.

As of Mitaka, the infra team won't have the resources available to
reasonably test py26, also the oslo team is dropping py26 support
from their libraries. since we rely on oslo for a lot of our work,
and depend on infra for our CI, we should drop py26 support too.

Because python creates pyc files during tox runs, certain
changes in the tree, like deletes of files, or switching
branches, can create spurious errors.

Now both the standard command "python setup.py build_sphinx" and
"tox -e docs" will build the documentation.

The changes:
* tox.ini: Fix docs section: Remove unneeded deps line, the general
  deps line is just fine. Enable the command, clean up before running
  sphinx and use the normal command for execution.
* pydocs.rst: This throw an error while building since
  troveclient.client.Dbaas does not exist, replace it.
* index.rst: Generate table of content. No need to include the files.
