Problem: API key of pipeline user is shown in Archivematica Storage Service UI

[sallain]

Expected behaviour
Keys should only be shown at the time of generation and then hidden.

Current behaviour
In the Storage Service UI, the API key of the pipeline is displayed on both the pipeline information page (Pipelines > [pipeline name]) and the pipeline edit page (Pipelines > [edit]). The same key is shown on the user page at Administration > User > Edit.

Steps to reproduce

Your environment (version of Archivematica, operating system, other relevant details)
