feat(sdl): can set credentials

[jzsfkzm]

One can select an image repository and enter credentials after this. Available in the SDL Builder, but not in the deployment UI.

ref #467

The credentials for private repos are optional, since not all repos are private. The way you implemented it is great, we just need to add a flag like "hasGpu" and conditionally add the validation. So a simple checkbox like the hasGpu to toggle the form controls should do it.

Is there a reason behind the canChangeCredentials? We would like to have it in all the SDL builder instances (SDL Builder page and new deployment page).

This is throwing and error in the build as the username and password are required.

I added the flag canChangeCredentials because I figured it is not needed for templates on the Deploy page. Now I see it is very much needed there too, so removed. Now it is all the same for Deploy and SDL Builder.
Added a checkbox with label "Private" on top the box, revealing credential fields only when you click it.

I just tested it locally and it works great, great work!
