v1.6.9

Final release for PVE 5.x. A couple bug fixes/improvements and Ceph improvements.

Please take this opportunity to upgrade your cluster to PVE 6.x (and then to 7.x if you can) if you have not done so already, as 5.x/Stretch is EOL.

#121 Add autoscale mode for Ceph pool configuration
#122 pve_ceph_mgr_group role variable to specify group of hosts to deploy the Ceph manager daemons on
#123 Correct list of required attrs for RBD storages
#124 Add the ability to disable hosts file management with pve_manage_hosts_enabled role variable
#128 Add CephFS storage type
#130 Ensure Ceph monitors only deploy on hosts in pve_ceph_mon_group
#131 Add pve_ceph_nodes role variable to limit which nodes Ceph is installed on.
#135 Replace fetch tasks with slurp and identify kernel in check mode
#136 Subscription patch fix (although this is outdated by the time of this release)
#139 Simplify patching of checked_command function
#140 (and subsequent fix in fbe315c) Manage /etc/hosts, even when clustering is disabled
#146 Throttle rebooting of cluster nodes when upgrading kernels (with optional pve_reboot_on_kernel_update_delay role variable)
