title: How to dynamically add engine at runtime in symmetricDS community version
body: <p>I use SymmetricDS community version to synchronize data between the server and the clients,the properties files of server and client are all in the same server machine /engines folder. Recently I wanted to add a new engine  in running symmetricds. When i  copyed propeties file of the new engine into the server machine /engines folder, the running symmetricds process didn't find it . The new engine didn't run. 
  Somebody said that he added new engine after Symmetric DS start using REST API - <a href="http://localhost:31415/api/engine/install" rel="nofollow noreferrer">http://localhost:31415/api/engine/install</a> available with 3.7.21 version,but he didn't show example. The API only supports POST method.If the api could realize adding engine at runtime , how to do it step by step?</p>
