This removes the fluentbit sidecars from the ceph-mon and ceph-osd
charts. Instead, we mount /var/log/ceph as a hostpath, and use the
fluentbit daemonset to target the mounted log files instead
This also updates the fluentd configuration to better handle the
correct configuration type for flush_interval (time vs int), as
well as updates the fluentd elasticsearch output values to help
address the gate failures resulting from the Elasticsearch bulk
endpoints failing
