ui: mutable deployments

[jgwhite]

What is this?

Addresses #1239

Adds the UI to display mutable deployments.

Mutable deployments are groups of deployment versions that utilize the same resources, where newer deployments in the same generation overwrite previous deployments (ie only latest version is deployed at the same deployment URL). This functionality was added to accommodate users' existing workflows.

What’s the plan?

• Create good fixture data in Mirage
• Implement the designs
• Ensure immutable deployments still render well
• Ensure destroyed deployments still render well
• Use the {{t ...}} helper for all text
• Write some light tests (we can probably borrow the dev Mirage config)
• Changelog entry

What does it look like?

Deployments list without destroyed deployments, note the grayed background of overwritten deployments + link to deployment only on latest

Deployments list with destroyed deployment

How do I verify it?

1. Check out this branch
2. yarn ember serve
3. Visit http://localhost:4200/tests
4. Verify all tests pass
5. Visit http://localhost:4200
6. Check the deployments under mutable-application in mutable-project
7. Verify there's no buggy behavior and everything else is untouched (check the builds section)

Very glad to see this move outside of the <ul>.

Technically I can’t approve this PR because I opened it, but it gets my 👍 nonetheless.

Looks good to me 👍🏻 I was able to build my own waypoint server container with the latest changes to test. Ran through a nomad jobspec and a k8s apply project and did a few waypoint ups for both.

Looks great and the attention to detail is :chefskiss:

Some minor changes highlighted that I think we should make

Should this text be in the translations/ file?

[sabrinako]

I started moving some of the text in this deployments.hbs file to the translations files, but @jgwhite said the checklist item about it on this PR was meant for the single deployment item template, not this overarching deployments template.

I added the other text to the translation file. Jamie and I discussed this specific block of text yesterday and agreed the paragraph breaks make it a bit more of a complex situation. It's a little out of scope for this PR, so we can add this text to the localization texts some other time.
