doc: Removed fragmented logging info. Consolidated into one doc.

Logging was variously described in the ceph configuration document,
a configuration reference, and a section in operations. Since
logging and debugging are generally used with troubleshooting,
I consolidated the docs and placed them in the troubleshooting
section. Also fixed the example and provided additional detail.

fixes: #3804
