Remove the misleading reference to this from the client
eviction page, it was never the right option to mention
there (my mistake).
Demote the option from LEVEL_ADVANCED to LEVEL_DEV as it
is hard to imagine a good reason for the user to change it.
Set a hard minimum of one hour, to make it harder to
corrupt` a system by setting it close to zero.
Remove the legacy definition of the field while we're at it.

The "session ls" and "session evict" are now
"client ls" and "client evict" (the old ones
are still there for backwards compatibility).
The automatic client eviction now emits
cluster logs that call the client by its
friendly name (usually the hostname).

This makes the code a bit awkward because we now have
4x paths through this function (blocking, noblocking, blacklisting,
nonblacklisting).

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.
