> There are times when the user wants to pause execution of the autoscaling policies because
he/she is performing some maintenance tasks. A cluster wide command can be used to suspend
the triggers indefinitely or for a specific amount of time.
> h3. Examples:
> Suspend the 'node_lost_trigger' until an explicit resume_trigger API is called:
> {code}
> curl -H 'Content-type:application/json' -d '{
> 	"suspend-trigger" : {
> 		"name" : "node_lost_trigger"
> 	}
> }' http://localhost:8983/solr/admin/autoscaling
> {code}
> Suspend all triggers until resumed by an explicit resume_trigger API call:
> {code}
> curl -H 'Content-type:application/json' -d '{
> 	"suspend-trigger" : {
> 		"name" : "#EACH"
> 	}
> }' http://localhost:8983/solr/admin/autoscaling
> {code}
> Suspend all triggers for 1 hour:
> {code}
> curl -H 'Content-type:application/json' -d '{
> 	"suspend-trigger" : {
> 		"name" : "#EACH"
> 		"timeout" : "1h"
> 	}
> }' http://localhost:8983/solr/admin/autoscaling
> {code}
