Introduce isPluginAvailable and selectPlugin

Summary:
Introduced API to replace the deprecated `selectPlugin` in Sandy.

The API can be used to navigate from `device plugin -> device plugin`, or` client plugin -> device / client plugin`

Introduced `isPluginAvailable` as well, so that the user interaction an be fine tuned in case the plugin is not disabled.
