Collector pods in CrashLoopback after upgrading to RHOL 5.7 in RHOCP4

Issue

• Collector pods are in CrashLoop after upgrading from RHOL 5.6 to 5.7.0

• After upgrading to RHOL 5.7.0, a new line is appended in the clusterlogging instance:

   collection:
     logs:
       fluentd: {}
       type: fluentd
     type: vector         <<< New line appended automatically
