Why are the changes needed?

I hope to obtain the master-slave status of AMS through HTTP and metrics.

Close #3994.

Brief change log

Introducing a member variable to identify the master/slave status of the AMS. The HealthCheckController and AmsServiceMetrics use this field to retrieve the AMS's master/slave status.

Address review feedback from @turboFei:
For hadoop2 profile, keep using the legacy Spark 3.3 by default
for better compatibility with Hadoop 2.x.

* Fix Spark version parameter name in README.md

Address review feedback from @turboFei:
Change -Dspark-optimizer.spark-version to -Dspark.version
