- set osd_memory_target_autotune=true to enable
- tuning is periodic (check every 10m by default)
- tuned values are reflected by osd_memory_target config options scoped
to the host
- only make a change if it appears that we will affect at least 1 of the
relevant OSDs
- attempt to clean out conflicting options. (This is imperfect, since any
manner of weirdly-scoped config options could be responsible; we only
attempt to clean out one scoped directly to the osd name.)

This tiny PR fixes an issue that I thought
I had squashed into PR#40914: a missing
word, "device", which was caught by Josh
Durgin during review.
Alas. I had not then caught it.
Here then it is, corrected at last.

This commit rewrites the entire "Remove an OSD"
section of the "OSD Service" chapter of the
cephadm book.
I got carried away and didn't break this one into
four smaller PRs, and I'm sorry in advance to
whomever ends up reviewing this. I'll break "Advanced
OSD Service Specifications", the next section in the
queue, into multiple sections.

This reorganizes the section "Deploy OSDs"
in the "OSD Service" chapter of the Cephadm
Guide. Two new sections, "Listing Storage
Devices" and "Creating New OSDs" gather
information under headings in a sensible way,
making the information more accessible to someone
skimming this Guide.
