Cheng Pan ac84d64d51 [CELEBORN-707][MASTER] Remove env CELEBORN_MASTER_HOST and CELEBORN_MASTER_PORT 
### What changes were proposed in this pull request?

Remove environment variables `CELEBORN_MASTER_HOST` and `CELEBORN_MASTER_PORT`, and makes `CELEBORN_LOCAL_HOSTNAME` takes effect on both master and worker.

### Why are the changes needed?

There are many different ways to configure the master/worker host and port, which makes the thing complex and inconsistent.

After this change,

#### master

1. cli args `--host` `--port` takes the highest priority
2. then lookup env `CELEBORN_LOCAL_HOSTNAME`
3. things are different when HA enabled and disabled
  3.1. when HA is disabled, lookup configurations `celeborn.master.host` and `celeborn.master.port`
  3.2. when HA is enabled, each node needs to know the whole cluster info,
     ```
     celeborn.master.ha.node.1.host clb-1
     celeborn.master.ha.node.1.port 9097
     celeborn.master.ha.node.2.host clb-2
     celeborn.master.ha.node.2.port 9097
     celeborn.master.ha.node.3.host clb-3
     celeborn.master.ha.node.3.port 9097
     ```
     in addition, `celeborn.master.ha.node.id=1` can be used to indicate the node id, otherwise, the master will try to bind each host to match the node id.

#### worker

1. cli args `--host` `--port` takes the highest priority
2. then lookup env `CELEBORN_LOCAL_HOSTNAME`

things are simple than the master case because each worker is not required to know others.

### Does this PR introduce _any_ user-facing change?

Yes.

### How was this patch tested?

UT.

Closes #1616 from pan3793/CELEBORN-707.
