Add warning state & tooltips in usage quota table

What does this MR do?

Changes are behind additional_repo_storage_by_namespace feature flag

In this iteration:

• a warning state to the usage quotas table based on the project usage data is added.
• The logic to determine if a project is in error state or warning state is hardcoded for the time being as this feature is still behind feature flag and the backend pieces are not in place yet. Eventually the calculations will be moved to backend.
• Tooltip for alert and warning icon is added.

Previous iterations:

• Update the Quotas Page table !43080 (merged)
• Introduce error state and remove collapsible section !43644 (merged)
