We currently use a `CopyToClipboard` component to display a Plugin manifest on ConsolePlugins details page.  It would be nice to use Monaco instead so that we get the benefit of syntax highlighting.  I prototyped an implementation that utilizes the existing `ResourceYAMLEditor`, but spadgett@redhat.com and I both wondered if it's confusing to use the `ResourceYAMLEditor` on the `Plugin manifest` tab since the tab sits next to the `YAML` tab that utilizes the same `ResourceYAMLEditor` component.  Maybe we need a simplified Monaco-containing component that more clearly indicates the contents are read-only and are not the standard YAML editor?

AC:

• Replace CopyToClipboard component for YAMLEditor (technically CodeEditor once) for displaying Plugin manifest on the ConsolePlugin details page. The YAMLEditor should be used in the read-only mode.
• Add integration tests which will check the Save button is not visible in the readonly mode and that CodeEditor and that the CodeEditor is disabled.
