The 'ceph-radosgw' process does not get reloaded properly after logrotate rotates the RGW logs.

Issue

• Logrotate does not reload the 'ceph-radosgw' process after rotating the RGW logs.

• This results in orphaned file handles which leads to lots of RGW log files created under /var/log/radosgw/.

• Restarting the 'ceph-radosgw' process manually fails as well.
