Fixes #1639 * Remove all traces of credential refresh from `RabbitMQ.Client` * Add `CredentialsRefresher`, which does not use timers, and calls refresh based on `ValidUntil` * Use `ICredentialsProvider` in the auth mechanisms, async * Pass `CancellationToken` around and correctly dispose Http objects (thanks @Tornhoof) * Use `SemaphoreSlim` * Refresh token at 1/3 the interval value. * Close connection mid-integration test for OAuth2 * Use OAuth2 for EasyNetQ.Management.Client in OAuth2 tests. * Create separate credentials provider for HTTP API requests. * Set RabbitMQ logging to debug for OAuth2 * Use `JsonPropertyName` * Use OAuth2 for HTTP API access. Thanks @MarcialRosales
