Manage critical jobs

Current Situation

• Users know about the criticality of certain jobs. They would like the criticality to be considered with the JOC Cockpit GUI and with a system monitor such as Nagios.
• However, there is no way to specify that a job is being considered critical.

Desired Behavior

• The JOC Cockpit should offer a list of criticalities (normal, minor, major) that a user can select for a given job. This operation should be available from the "Configurations" view with a listbox:
  • As a result a new job attribute "criticality" should be available:
    • minor criticality
    • major criticality
    • normal criticality
• The "History" view and related views should add a column "Criticality" that shows the normal, minor or major job criticality as different icons. 
• The JobScheduler Monitoring Interface should consider criticalities and should provide the new variables that holds the values "normal", "minor", "major".
  • JobScheduler Monitoring Interface variables:
    • ${MON_N_JOB_CRITICALITY} and the environment variable
    • %SCHEDULER_MON_TABLE_MON_N_JOB_CRITICALITY% (Windows), $SCHEDULER_MON_TABLE_MON_N_JOB_CRITICALITY (Unix)
