Cleanup headers and imports (ansible-collections#1738)

Cleanup headers and imports

SUMMARY
Mass update of imports, docs fragments and file headers

Many of the amazon.aws module_utils and docs fragments got moved about, update community.aws to reflect this.
Consistently apply the comment headers as documented at https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_documenting.html#python-shebang-utf-8-coding

COMPONENT NAME
ADDITIONAL INFORMATION
Header cleanup based upon:
https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_documenting.html#python-shebang-utf-8-coding

Begin your Ansible module with #!/usr/bin/python - this “shebang” allows ansible_python_interpreter to work. Follow the shebang immediately with # -*- coding: utf-8 -*- to clarify that the file is UTF-8 encoded.

and
https://docs.ansible.com/ansible/devel/dev_guide/developing_modules_documenting.html#copyright-and-license

After the shebang and UTF-8 coding, add a copyright line with the original copyright holder and a license declaration. The license declaration should be ONLY one line, not the full GPL prefix.
...
Additions to the module (for instance, rewrites) are not permitted to add additional copyright lines other than the default copyright statement if missing:
