/**
 * Integration plugin for Amplitude Analytics. Uses the analytics connector to
 * track events and get user identity.
 *
 * On initialization, this plugin attempts to read the user identity from all
 * the storage locations and formats supported by the analytics SDK, then
 * commits the identity to the connector. The order of locations checks are:
 *  - Cookie
 *  - Cookie (Legacy)
 *  - Local Storage
 *  - Session Storage
 *
 * Events are tracked only if the connector has an event receiver set, otherwise
 * track returns false, and events are persisted and managed by the
 * IntegrationManager.
