Dashboard server not able to pull metrics from clients running in docker env

## Issue Description

My docker containers are running in mesos cluster and they are sending metrics to dashboard using the docker container host. Sentinel dashboard server isn't able to pull metrics from clients

My query is :
I don't have a control where my docker containers will run in the mesos cluster.
How shall I set the value of this variable -Dcsp.sentinel.heartbeat.client.ip = xxx so that all my docker clients should be able to send metrics?

### Describe what happened (or what feature you want)

### Describe what you expected to happen

I expect sentinel dashboard server to collect metrics from all sentinel clients

### How to reproduce it (as minimally and precisely as possible)

### Tell us your environment

### Anything else we need to know?

Start by reviewing Sentinel's dashboard heartbeat and client IP configuration in the Java project, then examine how Docker containers in a Mesos cluster advertise reachable addresses. Reproduce the reported setup and verify that the dashboard collects metrics from all Sentinel clients; the issue does not name specific files or tests.
