Updating support for benchmark language versions

[mcopik]

Since our last release, certain language runtimes have been deprecated, and new ones have been added. In preparation for the next release, we now need to prune the language versions that are no longer supported and add new ones.

We should drop the support for Python/Node.js which are no longer deployable to clouds; this change should be done separately for each cloud, e.g., drop Python 3.7 where it's no longer supported.

Systems/languages to support;

• AWS, Python
• AWS, Node.js
• Azure, Python
• Azure, Node.js
• GCP, Python
• GCP, Node.js
• OpenWhisk, Python
• OpenWhisk, Node.js

Can i get some more guidance here like what files I should look up to?

@octonawish-akcodes All definitions of supported language versions are in the config/systems.json. To add support for new versions, you need to verify that Docker images build for it.

I tried to remove the AWS 3.7 python support since its no longer supported and raised a PR #198 @mcopik

Fixed with #198
