support org.apache.dubbo 2.7.x

current version of dubbo-rpc-jsonrpc is write for com.alibaba.dubbo version 2.4.x - 2.6.x

could someone rewrite the code for support org.apache.dubbo 2.7.x

change

```xml

com.alibaba
dubbo
${dubbo_version}
true

```

into

```xml

org.apache.dubbo
dubbo
${dubbo_version}
true

```

and rewrite the JsonRpcProtocol class there is no more com.alibaba.dubbo.rpc.protocol.AbstractProxyProtocol

Start by inspecting the Dubbo dependency declaration and the JsonRpcProtocol class, especially its use of the removed com.alibaba.dubbo.rpc.protocol.AbstractProxyProtocol. Update the dependency to org.apache.dubbo 2.7.x and adapt JsonRpcProtocol so the module supports that version and builds successfully.
