feat: [M3-9167] - Image Encryption Information

[bnussman-akamai]

Description 📝

• Adds a banner on the top of the Images pages that alerts users that Images are now encrypted by default 🔒
  • This is similar to the banner present for Kubernetes Node Encryption
• Updated the Image Table Row to show if an image is unencrypted 🔓
  • We are doing this because all Images will be encrypted going forward. UX and product decided we only should show if the Image is unencrypted. We don't show anything if the image is encrypted because it is now just default behavior of images.
• Removed imageServiceGen2 and imageServiceGen2Ga feature flags 🏴 because they have both been enabled for some time now. We can start showing the "Gen2" UI by default now.

Target release date 🗓️

In production by Feb 11th

How to test 🧪

Prerequisites

• I recommend testing this with and without the MSW
  • I updated the legacy MSW to mock all possible variations of an Image

Verification steps

• Legacy Images should show an unencrypted icon 🔓
  • Any image without the distributed-sites capability is considered unencrypted
• Verify there are no regressions to the Image Capture flow
  • You should be able to capture an image from a Linode in any region, but you should see a warning if the Linode's region does not support Image storage
• Verify there are no regressions to the Images landing tables
  • Verify both the Custom Images and Recovery Images tables work as expected with no regressions
