TS-3370: header_rewrite plugin uses dead continuation.
I have see this in production. As far as I can tell the problem is that the
remap rules can be reloaded, leading to creating new continuations to service
those rules. 60 seconds later the old continuations are deleted. If anything is
pending long enough it can still use an old (dead) continuation.
This change reference counts the config / continuation set and destroys the
old continuations when the last reference is dropped. Note that we can't use
the standard config registration mechanism because this is structured to have a
config instance per remap rule which would overwhelm that mechanism.
