* Update Jest snapshot

* Introduce new convention for config definition.

We need to define a way to acquire configuration schema as a part of
plugin definition. Having schema we can split steps of
config validation and plugin instantiation.

* Discover plugins, read their schema and validate the config.

Config validation finished before core services and plugins read from it.
That allows us to fail fast and have predictable validation results.

* Instantiate plugins using DiscoveredPluginsDefinitions.

* Update tests for new API.

* test server is not created if config validation fails

* move plugin discovery to plugin service pre-setup stage.

Set validation schemes in ConfigService.preSetup stage.
