Lucas Henry 393d09347e rgw: add option to disable synchronization traffic
Some users want to deploy two CephObjectStores for a single Zone. The first
configures RGWs to process the synchronization of the data, while the second
CephObjectStore configures the client RGWs.

Currently, this can be implemented by setting the RGW option
'rgw_run_sync_thread' in the 'rook-config-override' ConfigMap, though it is not
really user friendly.

Ref: https://docs.ceph.com/en/latest/radosgw/config-ref/#confval-rgw_run_sync_thread

This commit adds a new option in the CephObjectStore CRD as defined in issue
https://github.com/rook/rook/issues/12272. The new option
'disableMultisiteSyncTraffic' determine whether the operator should disable the
multisite sync threads for the RGWs.

If the option is set to 'false', or if the option is not specified, the operator
does nothing. This ensures that the multisite sync threads will not be enabled
for users that disabled explicitely the multisite sync threads either manually
or with the 'rook-config-override' ConfigMap.

This commit also recommends to use two objectstore when scaling Ceph Objectstore
Multisite replication, with one objectstore configured with disabled replication
traffic.
