RANGER-5680: Restructure audit services in docker compose and use OpenSearch as default Index Store

[kumaab]

What changes were proposed in this pull request?

• Use official Opensearch image from opensearchproject/opensearch version 3.7
• Configure Ranger with Opensearch Index Store as default in docker via audit services with an option to have index store Solr alternatively.
• Restructure all audit related services in docker-compose.ranger-audit-service.yml
• Add healthchecks for Kafka, kafka needs to be healthy before audit-ingestor and audit-dispatcher
• Updates the CI to bring up audit services with Opensearch as default Index Store.
• audit-dispatcher must depend on audit-ingestor to be healthy, until RANGER-5752 is resolved.

How was this patch tested?

• CI passing

• Additionally tested the following scenarios (from README.md):

# 1
export RANGER_DB_TYPE=postgres
export AUDIT_INDEX_STORE=opensearch
docker compose -f docker-compose.ranger.yml -f docker-compose.ranger-kafka.yml -f docker-compose.ranger-audit-service.yml -f docker-compose.ranger-usersync.yml -f docker-compose.ranger-tagsync.yml -f docker-compose.ranger-pdp.yml -f docker-compose.ranger-kms.yml up -d

# 2
export RANGER_DB_TYPE=postgres
export AUDIT_INDEX_STORE=solr
# manually update ranger-admin-install-postres.properties - one liner update
docker compose -f docker-compose.ranger.yml -f docker-compose.ranger-kafka.yml -f docker-compose.ranger-audit-service.yml -f docker-compose.ranger-usersync.yml -f docker-compose.ranger-tagsync.yml -f docker-compose.ranger-pdp.yml -f docker-compose.ranger-kms.yml up -d

# 3
export RANGER_DB_TYPE=postgres
export AUDIT_INDEX_STORE=solr
# manually update ranger-admin-install-postres.properties - one liner update
export COMPOSE_PROFILES=$AUDIT_INDEX_STORE,hdfs
docker compose -f docker-compose.ranger.yml \  
  -f docker-compose.ranger-kafka.yml \
  -f docker-compose.ranger-hadoop.yml \
  -f docker-compose.ranger-audit-service.yml up -d

• Verified Audits are flowing to Opensearch/Solr/HDFS.
• No denies are seen in Audits.
