    [FLINK-7724][REST][Tests][Metrics] add extra metrics to 
MetricStoreTest.setupStore

    ## What is the purpose of the change
    
    This is a pre-requisite for FLINK-7694
    
    I'm porting `JobMetricsHandler` to new REST endpoint. Part of the migration 
is to make sure the json generated before and after stay the same for UI to 
consume, and `JobMetricsHandler` is using `MetricStoreTest.setupStore()` to get 
a mocked `MetricStore`. 
    
    Here comes the problem. Currently, `MetricStoreTest.setupStore()` mocks all 
jobs with only one metric. We need to have at least one or two jobs with 
multiple metrics to make the mocked `MetricStore` can cover most use cases, and 
ensure the Json blob generated in `JobMetricsHandler` stay the same before and 
after migration.
    
    ## Brief change log
    
    - make two jobs in `MetricStoreTest.setupStore()` contain multiple metrics
    
    ## Verifying this change
    
    This change is already covered by existing tests
    
    ## Does this pull request potentially affect one of the following parts:
    
    none
