Keep separate record of nightly versions as soon as they get updated

[partouf]

Basic table and code to keep a record of nightly-version as soon as it gets updated on the EFS, requires a CE frontend mechanism to retrieve the version that was saved here.

Usage:

    versions = NightlyVersions()
    versions.update_version("/usr/bin/gcc", "0", "10.2.0", "10.2.0\nhello world")

    version = versions.get_version("/usr/bin/gcc")
    print(version)

Todo:

• Put version into table when check_exe is tested
• Figure out best way to handle the modified timestamp stuff
• Make optional somehow so that when users install nightly compilers on their own pc it won't try to call aws
• Proof of concept lambda to retrieve the version that the frontend can call

I have created a lambda for this, example: https://p6sqbrptgv4h32ru6aadaisw4q0ulazq.lambda-url.us-east-1.on.aws/?exe=%2Fusr%2Flocal%2Fbin%2Fgcc

https://us-east-1.console.aws.amazon.com/lambda/home?c=la&region=us-east-1&z=1#/functions/get_deployed_exe_version?tab=code

Can't actually put cloudfront in front of this though, needs to be an API Gateway thingy for that. Might be able to turn the lambda into api?

[partouf]

This only really could work because our frontend has the .exe for the compilers. Though it's no longer used by anything else in the frontend (for good reason). It's not great to have that dependency, but we just do not have the compiler id's on the infra side...

Unless I would add the properties reader like the library builder uses, we could do it. Then the question is, should the unique key then be the compiler id, or maybe add an extra attribute that has a list of id's somehow and can a dynamodb query select such a thing...

Now added, configured and tested with API Gateway and Cloudfront.

Todo

• Configure lambda, code, rights, gateway, cloudfront, etc in Terraform

Some comments, worth cahtting in Discord as most of it is porbably my miunderstandings

[partouf]

will merge this this weekend during the day and test it with check-installed and see anything bad happens
