Constraints on task execution, e.g. a execution group, allowed/disallowed nodes, etc.

Item Summary
Name	Type	Multiplicity	Description
group	property string	[0,1]	A group this task is a part of.
groupTaskLimit	property int	[0,1]	Number of tasks within the group that can be executed at once (cluster-wide).
secondaryGroup	container TaskExecutionGroupConstraintType	[0,-1]	Other limitations for the task.
retryAfter	property duration	[0,1]	In what time to retry after cluster-wide execution constraints are not met.

  A group this task is a part of. In the future, task execution groups will probably have more complex parameters. But for now, their only parameter is the (cluster-wide) member tasks limit. They are also referenced from NodeType when specifying execution limitations for them.
- groupTaskLimit
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Display order: 110
  
  Number of tasks within the group that can be executed at once (cluster-wide). Default is "unlimited". This parameter will be moved into separate task group object in a later version of midPoint.
- secondaryGroup
  
  Flags: RAM,runtime
  
  Multiplicity: [0,-1]
  
  Display order: 120
  
  Other limitations for the task.
- retryAfter
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Display order: 130
  
  In what time to retry after cluster-wide execution constraints are not met. The default is 1 minute.
