s3gw UI accessible in Longhorn for volume details (Epic)

[jhmarina]

What needs to be done

Add a link in the Longhorn user interface that allows users to access the s3gw UI in the volume details. It serves as an intermediate step towards the full integration of s3gw into the Longhorn UI. The expected features for the UI are:

• Bucket management
  • Create and delete a bucket
• Bucket access management
  • Ensure the user can create and delete/revoke bucket credentials (persistent and secure)
  • Ensure access management is through secret and access keys (and stored securely)

Although the s3gw UI will be loaded separately, it should closely resemble the Longhorn UI to ensure a seamless and cohesive user experience.

Acceptance Criteria

• A link in the Longhorn user interface provides access to the s3gw UI for volume details.
• Clicking on the link opens the s3gw UI in a new tab or window.
• The s3gw UI reflects the design principles, visual elements, and layout of the Longhorn UI to maintain UI consistency.
• The s3gw UI includes the following expected features:
  • Bucket Management:
    • Users can create and delete buckets.
  • Bucket Access Management:
    • Users can create, delete, and revoke bucket credentials.
    • Bucket credentials are securely stored and managed.
    • Access management is implemented using secret and access keys.
