Support default network modes, Update Python and Django Support

[rajadain]

Overview

In the case of default network modes, the networkMode attribute is not specified in the describe-task-definition response. For these cases, we add tolerance for when it isn't specified, defaulting to None, and skipping the AWSVPC configuration block.

BREAKING CHANGE

Also drops support for Django 2.2, 3.0, 3.1, and Python 3.6 and 3.7.

Testing Instructions

• Check out this branch: https://github.com/azavea/collab-for-children/tree/release/1.0
• Run ./scripts/manage ecsmanage showmigrations
  • Ensure it runs correctly

I see that new commits are being pushed up, so unsure if it is related. I followed the testing steps on the collab for children side and ran the suggested command at the root of the project, and got the following. Lemme know if I missed anything.

Ah right sorry, you need to run update after checking out that branch on collab-for-children to install the new dependency.

Tested and works as advertised. Looks like there is a changelog file at the root of this project- might be good to append an entry there. Also, do we need to cut a release for this project?

Will this affect Python versions used in projects?

[rajadain]

This is what we're testing against, but we didn't change any of the code, so users running Python 3.6+ should be able to run this no problem, just as they are now.

[rajadain]

Yes this will require a new release. Since we are dropping support for EOL'd Python and Django versions with this, I will do a major version upgrade. All existing projects should be unaffected since they are pinned to pull a current or older version, which does support their environment.

Awesome 🚀

[rajadain]

Thanks for reviewing! And sorry about the in-flight commits 🙈 I didn't realize the build would break until I opened the PR.

[aaronxsu]

No worries. All good.
