When testing < v10.2.1 with standby replay, I was often confused why the
MDS daemons would go into replay even when this was false.

I tried using these settings in tests without success. The correct config names
are prefixed with "mds".

...and restructure the "early adopters" page
into a "best practices" guide. Early adopters
are now just adopters :-)

When user is mounted a quota-restricted inode
as the root, report that inode's quota status
as the filesystem statistics in statfs.
This allows us to have a fairly convincing illusion
that someone has a filesystem to themselves, when
they're really mounting a restricted part of
the larger global filesystem.

Principally to tell people how to configure
standby, but more generally as a place to define
our terms for GIDs etc.

As 'fs remove_data_pool' is newly introduced command, let's
change it to 'fs rm_data_pool' immediately rather than introduce
another alias for it.

These are deliberately fairly sparse, because:
* These tools are for experts
* These tools may well be wrapped in a higher
level recovery tool that orchestrates parallel
workers at some stage.

Continue to run into people who see this and run away (occasionally to
less robust solutions) without understanding why.

Adding this at this time to give us a sensible place
to talk about the epoch barrier stuff. The eviction
stuff will probably get simplified once we add a mon-side
eviction command that handles blacklisting and MDS session
eviction in one go.

This clarifies how to deal with layouts in CephFS
using vxattrs. We can point people here if they
ask what they should use instead of the deprecated
`cephfs set_layout`.

- Add note to docs indicating that CephFS is not recommended for
production datasets.
- Add note to docs indicating that running CephFS with multiple MDS
servers is not currently recommended.
