* config: singular ANSIBLE_COLLECTIONS_PATH
Every other *_PATH setting in ansible is singular, and the traditional
$PATH variable is also singular despite containing a list of
directories. Let's be consistent both internally and with POSIX
tradition.
* update all ANSIBLE_COLLECTIONS_PATHS env references to be singular
* deprecate plural ANSIBLE_COLLECTIONS_PATHS setting
* Address compat issue for collection loading on py26
* Move import_module shim to utils for compat across the codebase
* Enable collection tests on py2.6
* Update changelog fragment
* Simplify code using sys.moduls
* Move compat to module_utils/compat/importlib
* Add back errantly deleted newline
* Remove hack comment

* Fix plugin names for collection plugins.
Add an integration test to verify plugin __name__ is correct for collection plugins.
* Fix collection loader PEP 302 compliance.
The `find_module` function now returns `None` if the module cannot be found. Previously it would return `self` for modules which did not exist.
Returning a loader from `find_module` which cannot find the module will result in import errors on Python 2.x when using implicit relative imports.
* add changelog
* sanity/units/merge fixes
