Toggle display of log source and of debug output in log view window

Current Situation

• Log output is created
  1. from the JobScheduler Master or Agent that writes messages e.g. about start and termination of tasks
  2. from any output to stdout/stderr that is caused by shell jobs
  3. from messages that are added by API jobs and by Monitors - this includes messages at info level and any debug level.
• Log output from the three sources is combined in the log file. When displaying log output that includes a large number of debug messages then the log is hard to read for users.

Desired Behavior

• The JOC Cockpit log view window should allow to select the log output from above sources 1) to 3), e.g. to limit log output to stdout/stderr.
• The JOC Cockpit log view window should allow to toggle between enabling and disabling the display of debug output.
  • The toggle should be available for all debug levels, e.g.
    • specifying debug1 will disable messages for any debug levels.
    • specifying debug3 wiill disable messages for debug levels debug1, debug2, debug3.
  • The toggle default value is to suppress debug messages.
