Register one or more applications by entering a Name,
Type and App URI of the application Jar.
You can also provide an optional metadata artifact URI.
The App URI & the Metadata Artifact URI are typically provided using the Maven coordinates of the Jar
(e.g. maven://io.spring.cloud:scdf-sample-app:jar:1.0.0.BUILD-SNAPSHOT),
but can be a local file or a docker image URI.
