Improve docker-compose config for Pulsar (#7335)

- fix graceful shutdown by using "exec bin/pulsar" when starting in a shell script
  so that OS signals can get delivered to Pulsar process to fix graceful shutdown
- simplify and fix configuration issues
- disable Pulsar Functions worker and related key-value storage service so that
  resource usage is reduced
- upgrade to use Pulsar 2.7.3 since 2.6.x isn't actively maintained
