UI usage instructions for docker components

In the Nexus UI when we browse to the details of a component in a docker repository, there is a Usage in the right panel of the UI. For example:

docker pull hello-world/latest

without repository endpoint.

This confused the customer's developers, because when they copy the usage instructions as provided without adding a host or port to the command they are unable to pull a docker component.

Customer requests that the UI provide the ability to add proper endpoint to each repository. "Without endpoint this information useless and just increasing number of IT calls."
