Here I think we could use `MesosEntrypointUtils#loadConfiguration(cmd)`.

https://github.com/apache/flink/pull/4555

[FLINK-6630] [Mesos] Implement FLIP-6 MesosAppMasterRunner

## What is the purpose of the change
Implement Mesos runners for FLIP-6.

[FLINK-6630] [Mesos] Implement FLIP-6 MesosAppMasterRunner
[FLINK-6631] [Mesos] Implement FLIP-6 MesosTaskExecutorRunner

## Brief change log

- bin: new entrypoints scripts for flip-6
- ClusterEntrypoint: Refactor the shutdown method
- ClusterEntrypoint: Install default FileSystem (for parity with legacy 
entrypoints)
- ClusterEntrypoint: new MesosJobClusterEntrypoint, 
MesosSessionClusterEntrypoint, MesosEntrypointUtils, MesosTaskExecutorRunner
- MesosServices: enhanced with artifactServer, localActorSystem
- MesosResourceManager: Fallback to old TM params when UNKNOWN resource 
profile is provided
- MesosResourceManager: config setting for taskmanager startup script 
(mesos.resourcemanager.tasks.taskmanager-cmd)
- test: added a 'noop' job graph for testing purposes

## Testing
This change involves manual testing and is verified as follows:
1. Configure Flink to use the FLIP-6 TM runner.  
```
mesos.resourcemanager.tasks.taskmanager-cmd: 
$FLINK_HOME/bin/mesos-taskmanager-flip6.sh
```
2. Configure other Mesos options as normal.
3. Launch a job-specific cluster using `mesos-appmaster-flip6-job.sh`:
```
$ bin/mesos-appmaster-flip6-job.sh 
-Dflink.jobgraph.path=/flink-tests/src/test/resources/jobgraphs/streaming-noop-3.graph
```
