As a Cockpit user

Given:

• I am on the Process Definition Runtime View
• and there is a lot of executions (> 400.000) in the execution table

When:

• I switch off by default the activity instance statistics

Then:

• the diagram overlay with activity instance statistics is not shown

So that

• the execution of the corresponding query does not hang in case of large data

In addition:

• I can toogle a button to show the statistics
• in addition there is a configuration option to enable/disable the diagram overlay activity instance statistics
• by default the diagram overlay activity statistics are enabled
• the configuration option is documented
