THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Connect has a REST API where clients can easily ask for which connectors are loaded by the Worker. SMTs are popular feature, and it would be great to have a programmatic way to ask the worker which SMTs it has loaded.
Currently the best way to do this is by parsing logs.verify which SMTs the worker has loaded is to visually parse logs. This sometimes impossible for a long-running worker, and tedious otherwise. It also prevents programmatic querying and verification that SMTs loaded.
Existing endpoint to get Connectors is actually called "GET /connector-pluings", implying it should be used for all plugins. In reality, Connectors are just one type of plugin: Other types include Simple Message Transformations (SMTs), Converters, HeaderConverters, ConfigProviders, and RestExtensions (loaded by the "DelegatingClassLoader").
