Move test samples to reduce setuptools warnings

Previously there are a lot of warning messages of setuptools in the log
files of tox jobs. This is mainly caused by test samples because these
are in python codes directories.

This patch moves test samples from under
{heat-translator_root}/translator/tests to under
{heat-translator_root}/samples/tests.

This patch also contains the following changes:
- Remove "skipsdist = True" from tox.ini
- Fixed usage.rst command example
