Original commit message:

Subject: [PATCH] ceph-config: fix calculation of num_osds

The number of OSDs defined by the lvm_volumes variable is added to num_osds in task Count number of osds for lvm scenario. Therefore theses devices must not be counted in task
Set_fact num_osds (add existing osds).
There are currently three problems with the existing approach:

1. Bluestore DB and WAL devices are counted as OSDs
2. lvm_volumes supports a second notation to directly specify logical volumes instead of devices when the data_vg key exists. This scenario is not yet accounted for.
3. The difference filter used to remove devices from lvm_volumes returns a list of unique elements, thus not accounting for multiple OSDs on a single device

The first problem is solved by filtering the list of logical volumes for devices used as type block.
For the second and third problem lists are created from lvm_volumes containing either paths to devices or logical volumes devices. For the second problem the output of ceph-volume is simply filtered for lv_paths appearing in the list of logical volume devices described above.
To solve the third problem the remaining OSDs in the output are compiled into a list of their used devices, which is then filtered for devices appearing in the list of devices from lvm_volumes.

Fixes: ceph/ceph-ansible#7435

iThis does not seem to move along upstream, so I propose to add the patches in our container build
