Removed the temp work around from subnet module
updated all tests with bz decorator
Added new make_product method to factory.py.

Added a new make_product method to handle CLI tests.
Remove empty "" from standard CLI output.

When a field does not have any data, hammer cli returns an empty ""
which then gets converted to u'""'. Trying to assert if a field is None
or if its length is equal to zero was failing, so now I replace '""'
with ''.
Adding CLI tests for Products.

This handles Issue #182 and adds CL CRUD tests for hammer product command.
Added more CLI tests for Products.

Added CRUD CLI tests for products. This closes issue #182.
