Add support of the time module in Starlark Processor

[essobedo]

Required for all PRs:

• Associated README.md updated.
• Has appropriate unit tests.

fixes #9000

Motivation

The upstream project starlark-go has added a new module called time to support dates and durations, thus the goal of this feature request is to add the support of this new module in the Starlark Processor.

Modifications

• Upgrade the version of go.starlark.net
• Import the module time of go.starlark.net in the Starlark Processor
• Add a test showing how to parse a date and a duration and how to create a timestamp in seconds
• Refer the tests into the README.md

Result

In Starlark script, we can now import the module with load('time.star', 'time'), and then have access to all the corresponding building functions and constants.

NB: Beware the built-in function from_timestamp only supports timestamps in seconds.

Hey @essobedo, thanks for all your effort regarding starlark! You are my hero!
Regarding this PR I think it tries to achieve the same as #7742 and also suffers from the same problems regarding the update of protobuf. How should we proceed? Should I close #7742 in favor of this PR?

[essobedo]

@srebhan Hi, if you don't mind closing #7742 in favor of this PR, it would be great

[essobedo]

@srebhan about the build failure on make tidy, I don't really get it, it doesn't fail on my side. Any idea how to fix it?

[srebhan]

Ok closed. Please note, that your build errors/dependency hell is resolved with #8937 being merged (tested locally).

@essobedo are you using the Go version 1.16+ locally when running `make tidy'? If not could you update Go to the latest version and run it again and push the changes.

@sspaink No, I'm using 1.15.8, let me upgrade it and try again, thank you for your help

[essobedo]

@sspaink it seems to work now, many thanks

[sspaink]

The failing of the job 'share-artifacts' is unrelated to this PR, will be fixed soon but will require a re-base to get the new config. Sorry about that.
Ok should be resolved now, will require a re-base to get a check mark but it isn't required. sorry for the confusion.

Great work on the PR!

@essobedo Do you think you could add time.star and math.star information to the Starlark readme libraries section?

[essobedo]

@sjwang90 yes of course, I will propose a PR asap
