vinyl: ignore quota timeout on replication

If vinyl fails to do memory dumps in time on a replica (e.g. it ran
out of disk space), replication will stop forever with an error, and
the admin will have to call box.cfg() to restart replication. Since
replication is asynchronous anyway, we shouldn't stop it on vinyl
timeout - it isn't critical as the replica will recover as soon as
the admin fixes the problem (e.g. frees up some disk space). Let's
ignore vinyl timeout altogether for applier fibers (currently, we
ignore it only on join) - the admin can monitor how badly a replica
lags behind the master via box.info.replication lag/idle.

Closes #3087
