Optional. The percentage threshold that a load balancer will begin to
send traffic to failover backends. If the percentage of endpoints in a
MIG/NEG is smaller than this value, traffic would be sent to failover
backends if possible. This field should be set to a value between 1
and 99. The default value is 50 for Global external HTTP(S) load balancer
(classic) and Proxyless service mesh, and 70 for others.
