ReplicationService (Lucene 9.0.0 replicator API)

java.lang.Object
- org.apache.lucene.replicator.http.ReplicationService

```
public class ReplicationService
extends Object
```
A server-side service for handling replication requests. The service assumes requests are sent in the format /<context>/<shard>/<action> where
- context is the servlet context, e.g. REPLICATION_CONTEXT
- shard is the ID of the shard, e.g. "s1"
- action is one of ReplicationService.ReplicationAction values
For example, to check whether there are revision updates for shard "s1" you should send the request: http://host:port/replicate/s1/update.
This service is written like a servlet, and perform(HttpServletRequest, HttpServletResponse) takes servlet request and response accordingly, so it is quite easy to embed in your application's servlet.
WARNING: This API is experimental and might change in incompatible ways in the next release.
