Revert use of DaemonSet for logstash
Using a DaemonSet for logstash is problematic for HA k8s because pods are being scheduled on etcd and orchestration nodes where we do not want them. Reverting back to a Deployment with a default of 5 replicas instead. Issue-ID: LOG-181 Change-Id: I8bbc165a6f23c31b372320c3a94181c689f1baef Signed-off-by: Gary Wu <gary.i.wu@huawei.com>
