* allow `Wait()`ing on the supervisor In the event the plugin supervisor shuts down a plugin for crashing too many times, the new `Wait()` interface allows the `ActivatePlugin` to accept a callback function to trigger when `supervisor.Wait()` returns. If the supervisor shuts down normally, this callback is invoked with a nil error, otherwise any error reported by the supervisor is passed along. * improve plugin activation/deactivation logic Avoid triggering activation of previously failed-to-start plugins just becase something in the configuration changed. Now, intelligently compare the global enable bit as well as the each individual plugin's enabled bit. * expose store to manipulate PluginStatuses * expose API to fetch plugin statuses * keep track of whether or not plugin sandboxing is supported * transition plugin statuses * restore error on plugin activation if already active * don't initialize test plugins until successfully loaded * emit websocket events when plugin statuses change * skip pruning if already initialized * MM-8622: maintain plugin statuses in memory Switch away from persisting plugin statuses to the database, and maintain in memory instead. This will be followed by a cluster interface to query the in-memory status of plugin statuses from all cluster nodes. At the same time, rename `cluster_discovery_id` on the `PluginStatus` model object to `cluster_id`. * MM-8622: aggregate plugin statuses across cluster * fetch cluster plugin statuses when emitting websocket notification * address unit test fixes after rebasing * relax (poor) racey unit test re: supervisor.Wait() * make store-mocks
