🐙 octavia-cli: list connectors

[alafanechere]

What

We want to display a list of existing sources and destinations connectors that can then be created with (yet to be implemented) octavia create commands.

How

• Declare two new subcommand groups: octavia > list > connectors
• Implement sources and destinations commands in the connectors group to list existing sources and destinations in an Airbyte instance. Make use of a Definitions abstract class to
• Expose the created commands : octavia list connectors sources + octavia list connectors destinations

Recommended reading order

1. octavia-cli/octavia_cli/entrypoint.py > Addition of list subcommand to octaviacommand group
2. octavia-cli/octavia_cli/list/commands.py > Declaration of the list and connectors command groups + sources and destinations commands
3. octavia-cli/octavia_cli/list/definitions.py Implementation of a Definitions abstract class to retrieve and display sources and destinations lists.
4. octavia-cli/unit_tests/test_list/* write unit tests for the new code.
5. octavia-cli/unit_tests/test_entrypoint.py update entrypoint test.

🚨 User Impact 🚨

octavia --airbyte-url="https://demo.airbyte.io" list connectors sources and octavia --airbyte-url="https://demo.airbyte.io" list connectors destination are now available commands and display the following output.

@alafanechere these new commands are listing the current version of the containers in the user instance OR the latest version in Docker hub?

[marcosmarxm]

some initial comments! It's amazing :D

[marcosmarxm]

Maybe a base class to control the CLI specification where users can configure too.

[alafanechere]

Yes, you're right. I did not want to make premature optimizations and think that this refactoring need and the right place to put these functions will become more evident during the implementation of other commands.

[alafanechere]

I opened the next PR (draft) that implements a lot of the TODO mentioned in this one and make heavy use of inheritance to have a shared logic between listing commands: #9642

We are using this endpoint with I think merges GitHub's source_definitions.yaml file and the custom connector.

Looks good to me! Though it looks like there are some build errors that should be fixed before merging

[alafanechere]

Thank you @marcosmarxm and @lmossman for the review and your valuable feedback!
The build error is due to some formatting inconsistencies between isort in pre-commit hook and isortFormat task ran by ./gradlew format (line length parameter is not set to 140 in pre-commit). I discarded pre-commit changes for isort in this PR, and will check if we can align formatting task and pre-commit hook parameters in another PR, because it might affect other parts of the project.
