Allow tools from public and private Amazon ECR to be registered

[kathy-t]

Split out from #4283 (part 2). The regular expression for Amazon ECR currently doesn't support public Amazon ECR and it may be too strict.

Notes to reviewer:

• Test that you can register a public and private Amazon ECR tool in the UI
• Test that you can register a public and private hosted Amazon ECR tool in the UI
• Amazon ECR image repositories can contain multiple slashes, like foo/bar/potato. Test that when registering an Amazon ECR tool, you can use an image repository that contains multiple slashes

Was able to create public and private Amazon ECR tools both from external source control

Was able to create both for hosted workflows

Was able to create docker images with multiple slashes (which still seems like a bad idea, but thats on Amazon)

Thanks for being so thorough!
