Fix collection loader and add unit tests. (#58701)
* Use `compile` before `eval` in collection loader.

This fixes two issues:

1. File names are available when tracing execution, such as with code coverage.
2. Future statements are not inherited from the collection loader.

* Add unit tests for collection loading.

These tests verify several things:

1. That unit tests can import code from collections when the collection loader is installed.
2. That tracing reports the correct file and line numbers (to support code coverage).
3. That collection code does not inherit __future__ statements from the collection loader.

* Update unit test handling of the collection loader.

Since the collection loader is installed simply by importing ansible.plugins.loader,
we may already have a collection loader installed when the test runs. This occurs if
any other tests are collected which use that import during collection. Until that code
is moved into an initialization function to avoid loading during import, the unit tests
will need to replace any existing collection loaders so that they reflect the desired
configuration.

* Insert into sys.modules before calling exec.

This is a requirement of PEP 302.

It will prevent recursion errors when importing the current module or using a relative import.

* Use the correct value for __package__ in modules.

This allows using relative imports in collections.

* Add warning about modifying code for trace test.

* Add test for relative import in collection.

* Add __init__.py to collection to satisfy pylint.

The relative-beyond-top-level rule in pylint may not be appropriate for collections.
However, until that rule is disabled for collections this will keep tests passing.

Ansible
*******

Ansible is a radically simple IT automation system. It handles
configuration management, application deployment, cloud provisioning,
ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex
changes like zero-downtime rolling updates with load balancers easy. More information on `the Ansible website <https://ansible.com/>`_.

Design Principles
=================

*  Have a dead simple setup process and a minimal learning curve.
*  Manage machines very quickly and in parallel.
*  Avoid custom-agents and additional open ports, be agentless by
   leveraging the existing SSH daemon.
*  Describe infrastructure in a language that is both machine and human
   friendly.
*  Focus on security and easy auditability/review/rewriting of content.
*  Manage new remote machines instantly, without bootstrapping any
   software.
*  Allow module development in any dynamic language, not just Python.
*  Be usable as non-root.
*  Be the easiest IT automation system to use, ever.

Use Ansible
===========

You can install a released version of Ansible via ``pip``, a package manager, or
our `release repository <https://releases.ansible.com/ansible/>`_. See our
`installation guide <https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html>`_ for details on installing Ansible
on a variety of platforms.

Red Hat offers supported builds of `Ansible Engine <https://www.ansible.com/ansible-engine>`_.

Power users and developers can run the ``devel`` branch, which has the latest
features and fixes, directly. Although it is reasonably stable, you are more likely to encounter
breaking changes when running the ``devel`` branch. We recommend getting involved
in the Ansible community if you want to run the ``devel`` branch.

Get Involved
============

*  Read `Community
   Information <https://docs.ansible.com/ansible/latest/community>`_ for all
   kinds of ways to contribute to and interact with the project,
   including mailing list information and how to submit bug reports and
   code to Ansible.
*  Join a `Working Group
   <https://github.com/ansible/community/wiki>`_, an organized community devoted to a specific technology domain or platform.
*  Submit a proposed code update through a pull request to the ``devel`` branch.
*  Talk to us before making larger changes
   to avoid duplicate efforts. This not only helps everyone
   know what is going on, it also helps save time and effort if we decide
   some changes are needed.
*  For a list of email lists, IRC channels and Working Groups, see the
   `Communication page <https://docs.ansible.com/ansible/latest/community/communication.html>`_

Branch Info
===========

*  The ``devel`` branch corresponds to the release actively under development.
*  The ``stable-2.X`` branches correspond to stable releases.
*  Create a branch based on ``devel`` and set up a `dev environment <https://docs.ansible.com/ansible/latest/dev_guide/developing_modules_general.html#common-environment-setup>`_ if you want to open a PR.
*  See the `Ansible release and maintenance <https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html>`_ page for information about active branches.

Roadmap
=======

Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8).
The `Ansible Roadmap page <https://docs.ansible.com/ansible/devel/roadmap/>`_ details what is planned and how to influence the roadmap.

Authors
=======

Ansible was created by `Michael DeHaan <https://github.com/mpdehaan>`_
and has contributions from over 4000 users (and growing). Thanks everyone!

`Ansible <https://www.ansible.com>`_ is sponsored by `Red Hat, Inc.
