Docker Promote Tag

Used to "promote" a Docker image tag, such as promoting from "development" to "test". Will calculate the "source" tag for a given target one. The default mapping can be overriden, and you can always provide your own "source" to override any mapping.

Example: the "source" for the "staging" tag (environment) is "test".

Some notes:

• Will fallback to docker hub registry (if none is provided)
• Image name will default to the current repository name
• Tag mapping is case insensitive
