DeviceLogs plugin to Sandy

Summary:
Converted the DeviceLogs plugin to sandy.

Kept logic and UI the same (so same batching, localstorage mechanisms etc). But used sandy api's for log subscribing, state, and separating the logical part of the component from the UI.

Note that some mechanisms work slightly different, like deeplinking and scrollToBottom handling, to reflect the fact that plugins are now long lived
