imageName option is confusing

What happened?

Given the following (awsx) code, I would expect the image tag in the ecr to be latest. Instead it is set to the imageName value (i.e. “mitch-image”).

Am I mistaken about how this should work? Or is this a bug?

const image = new awsx.ecr.Image("my-image", {
    imageName: "mitch-image",
    repositoryUrl: repository.url,
    context: "./app", // Path to your Dockerfile and application directory
    imageTag: "latest",
});

Checking up on this, https://github.com/pulumi/pulumi-awsx/issues/1171 introduced the imageName option but it's behaviorally identical to imageTag option at the moment, we probably only want one of those, not two. We should consider retracting 1171.

Ideally we should remove imageName and keep only imageTag.

Image name usually refers to the part before the tag (see docker docs), but here the imageName is used like a tag.

For ECR, the image name is set when creating the repository. So if users want different image names, they need to create different repos. If they just want different tags, then they can set the imageTag property on awsx.ecr.Image

If we're touching this, we should also try to fix the resource name of the Image. I just saw that's it's using the TAG as the resource name: https://github.com/pulumi/pulumi-awsx/blob/0cbb50c6c06a988fa319dd4afbe1a1d6ee1dcfa0/awsx/ecr/image.ts#L40-L44 https://github.com/pulumi/pulumi-awsx/blob/0cbb50c6c06a988fa319dd4afbe1a1d6ee1dcfa0/awsx/ecr/image.ts#L89

But you can have the same tag (e.g. latest) across many different images, which would lead to duplicate URN errors right now if they're in the same stack.
