Show secret scope and keys in overview table

[johannes-b]

Use case

Current screen:

As a user, I would like to see the specified scope of a secret and the keys in the secret after creating a secret:

Details:

• Scope: Single value
• Keys: List of values
• The GET /secrets endpoint provides this information

{
  "Secrets": [
    {
      "name": "slack-secret",
      "scope": "keptn-webhook-service",
      "keys": [
        "webhook-identifier"
      ]
    }
  ]
}

Definition of Done:

• UI test cover the updated table
• Feature is implemented
• Screenshots in docs are updated (if needed)
