URL: https://github.com/apache/flink-kubernetes-operator/pull/814

   ## What is the purpose of the change
   
   Currently, autoscaler standalone doesn't support set [autoscaler 
options](https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-release-1.8/docs/operations/configuration/#autoscaler-configuration).
 We must set them at job level when we use autoscaler standalone. It's not 
convenient if platform administrator wanna change the default value for some 
autoscaler options, such as:
   
   - job.autoscaler.enabled
   - job.autoscaler.metrics.window
   - etc
   
   ## Brief change log
   
   - [FLINK-35105][autoscaler] Support setting default Autoscaler options at 
autoscaler standalone level
     - This Jira supports setting Autoscaler options at autoscaler standalone 
level, it's similar with flink kubernetes operator.
     - The  autoscaler options of autoscaler standalone will be as the base 
configuration, and the configuration at job-level can override the default 
value provided in the autoscaler standalone.
   
   ## Verifying this change
   
   - Improved the 
`FlinkClusterJobListFetcherTest#testFetchJobListAndConfigurationInfo` to check 
baseConf is empty and not empty.
