Fix clone problem

When clone happened, the origin header also will be updated in GenericObjectMap,
so the new header wraper(StripObjectHeader) should be updated too.

osd/ReplicatedPG: fix whiteouts for other cache mode

We were special casing WRITEBACK mode for handling whiteouts; this needs to
also include the FORWARD and READONLY modes.  To avoid having to list
specific cache modes, though, just check != NONE.

osd/ReplicatedPG: fix trim of in-flight hit_sets

We normally need to stat the hit_set to know how many bytes to adjust the
stats by.  If the hit_set was just written, we will get ENOENT.

Get the obc instead, which will either get the in-memory copy (because the
repop is still in flight) or load it off of disk.

mon/MonClient: remove stray _finish_hunting() calls

Callig _finish_hunting() clears out the bool hunting flag, which means we
don't retry by connection to another mon periodically.  Instead, we send
keepalives every 10s.  But, since we aren't yet in state HAVE_SESSION, we
don't check that the keepalives are getting responses.  This means that an
ill-timed connection reset (say, after we get a MonMap, but before we
finish authenticating) can drop the monc into a black hole that does not
retry.

Instead, we should *only* call _finish_hunting() when we complete the
authentication handshake.

osd: throttle snap trimmming with simple delay

This is not particularly smart, but it is *a* knob that lets you make
the snap trimmer slow down.  It's a flow and a simple delay, so it is
adjustable at runtime.  Default is 0 (no change in behavior).

Partial solution for #6278.

rgw: cut short object read if a chunk returns error

Fixes: #8289
Backport: firefly, dumpling
When reading an object, if we hit an error when trying to read one of
the rados objects then we should just stop. Otherwise we're just going
to continue reading the rest of the object, and since it can't be sent
back to the client (as we have a hole in the middle), we end up
accumulating everything in memory.
