Bug 2159850

[DOC] Ceph5 Troubleshooting Guide -  need to fix some explanations in the Ceph5 Troubleshooting Guide

I understood that Red Hat Ceph Storage 5 is supported on container-based deployments only.
Ι think There may be missing about container-based deployments on the Troubleshooting guide

So, I submitted the BZ, Would you please confirm it ?

Describe the issue:
 - 1.6. Understanding Ceph logs
 - 2.2. Ceph subsystems
 - 5.2.6. Down OSDs
 - 5.4. Mounting the OSD data partition
 - 9. Troubleshooting Ceph objects
 - 9.3. Troubleshooting low-level object operations

Describe the task you were trying to accomplish:
Suggestions for improvement:
> 1.6. Understanding Ceph logs
=> I think It need a description of the container such as "1.4. Understanding Ceph logs" on the Ceph4 troubleshooting guide [1].

> 2.2. Ceph subsystems
=> I think It need a description of the container such as "2.2. Ceph subsystems of Note"[2] the Ceph4 troubleshooting guide.

> 5.2.6. Down OSDs
=> Because it is a description of OSD using bare metal and file system,
=> I think it need a description using container and bluestore.

> 5.4. Mounting the OSD data partition
=> Because it is a description of OSD using bare metal and file system,
=> I think it need a description using container and bluestore.

> 9. Troubleshooting Ceph objects
=> I think it need a description of the container such as the Ceph4 troubleshooting guide ("10.4 Troubleshooting Ceph objects in a containerized environment"[3]).

> 9.3. Troubleshooting low-level object operations
 => I think it need a description loging in to the Cephadm shell such as "9.2. Troubleshooting high-level object operations"[4].
    Part 9.3.2 , 9.3.6 and 9.3.8 are missing the description of "# cephadm shell".
