Add UI table with Cluster specs and action buttons

[ChristianZaccaria]

Issue link

Jira: https://issues.redhat.com/browse/RHOAIENG-12526

What changes have been made

• Added UI table that will display existing clusters with their specs, and handle user interactions which include:
  • Selecting a cluster.
  • Deleting the selected cluster.
  • Opening in a new tab the Ray Dashboard of the selected cluster.
  • Opening in a new tab the Ray Dashboard Job view of the selected cluster.
• Formatted table to merge req~lim resources into one column.
• Formatted status field to change text color and add an icon based on the cluster status.
• Added unit tests.
• Added outputs.
• Updated Ray model with cpu requests and cpu limits.

TODO:

• Add view_clusters to guided-notebooks by default? - Given Cluster Up and Cluster Down widgets will appear by default, I think it's a good idea to immediately encourage the user to use (and be aware) of this feature. We don't need to trigger the buttons for test-guided-notebooks tests as it will be covered by ui-notebooks-test tests. Only the expected outputs would have to be updated.
• Enhance unit tests.
• Add to UI tests
• Implement TODO left in widgets.py file. [ ✔️ ]

Verification steps

Install the codeflare-sdk and import:

from codeflare_sdk import view_clusters

There are several items to test which include:

• Create several clusters.
• Select a cluster.
• Click on each button.
• Switch clusters and click on each button.
• Verify spec displayed.
• Verify output.
• Repeat with AppWrappers.

Checks

• I've made sure the tests are passing.
• Testing Strategy
  • Unit tests
  • Manual tests
  • Testing is not required for this change

Just a few nits looks good other than that. I will physically test this now but I just have another annoying nit on top of all of this.

Can you add head comments for all of the new functions of the wdgets.py file? Similar to what you have done here.

@ChristianZaccaria can you run the pre-commit run --all-files command on your next commit :)
For future ease you can run pre-commit install within the project and every time you make a commit the pre-commit hook will run stopping you from commiting if your files are not up to the format.

@ChristianZaccaria The ray image is fixed now so E2E should pass. Can you rebase?

[ChristianZaccaria]

Remaining enhancements will be made in the scope of the Jira "Refactor ipywidgets into a separate module" from the Refactor CodeFlare-SDK epic.

This includes:

• Enhance unit tests to increase coverage.
• Convert widgets to its own class.
• Find a way of leveraging cluster.down to re-use code.
