* Stores a cache of inactive connections so their subscriptions are recovered on reconnections * Adds test for getUserIDsForWorkspace and simplify messages through helpers * Make the plugin websocket client more resilient * Remove missed event callback and limit ws state polling to one at a time * Add read lock for the plugin adapter and guarantee atomic ops on inactiveAt * Add mutex to the plugin adapter client and tests to cover for races * Split plugin adapter mutex in two and use them to lock only on data access * Group plugin adapter fields by the mutex that's guarding them
