msg/Pipe: fix tight reconnect loop on connect failure

The fault() call in connect should not set onread=true since connect is
effectively a write path.  This was forcing the writer() into a tight
loop that repeatedly would call connect(); not very polite.

Changing that, we want to avoid treating this as a normal fault (with the
failure callback) and instead back off.

librados: add assert_exists guard operation

Add a guard operation for writes that asserts that the object already
exists.  To avoid requiring new functionality on the OSD side, implement
this by including a STAT operation, and discard the results on the
client side.

librbd: use assert_exists() to simplify copyup check

Previously we would explicitly STAT the object to see if it exists before
sending the write to the OSD.  Instead, send the write optimistically, and
assert that the object already exists.  This avoids an extra round trip in
the optimistic/common case, and makes the existence check in the initial
first-write case more expensive because we send the data payload along.
