e858dae187 Fix SIGSEGV for distributed queries on failures 
Since after pull(), cancel() will be called, and this will lead to
SIGSEGV, since there is no exception, but has_exception was not reseted
in pull()

6965ac26c3 Distributed: Add ability to delay/throttle INSERT until pending data will be reduced 
Add two new settings for the Distributed engine:
- bytes_to_delay_insert
- max_delay_to_insert

If at the beginning of INSERT there will be too much pending data, more
then bytes_to_delay_insert, then the INSERT will wait until it will be
shrinked, and not more then max_delay_to_insert seconds.

If after this there will be still too much pending, it will throw an
exception.

Also new profile events were added (by analogy to the MergeTree):
- DistributedDelayedInserts (although you can use system.errors instead
  of this, but still)
- DistributedRejectedInserts
- DistributedDelayedInsertsMilliseconds

15f7459cae Distributed/DirectoryMonitor: protect metric_pending_files with metrics_lock 
Since there is local value, that is not atomic, anyway we already have
lock for metrics, so it is fine.

fcf49a4914 Distributed: Calculate counters for async INSERT at INSERT time 
Previous patch fixes the inaccuracy, but it's done using iterating over
directory on each request (to system.distribution_queue or to check
bytes_to_throw_insert), and like previous patch alredy stated, it may
have pretty huge overhead (especially when you have lots of distributed
files pending).

This patch remove that recalculation (but it will still be done, and
if there is different, there will be a log message), and replace it with
proper account at INSERT time (and after file has been sent, or marked
as broken).

b43046ba06 Distributed: More accurate distribution_queue counters 
So now system.distribution_queue will show accurate statistics, so tests
does not requires sleep anymore.

But note that with too much distributed pending this will iterate over
all directories.

b5a5778589 Distributed: Add ability to limit amount of pending bytes for async INSERT 
Right now with distributed_directory_monitor_batch_inserts=1 and
insert_distributed_sync=0 INSERT into Distributed table will store
blocks that should be sent to remote (and in case of
prefer_localhost_replica=0 to the localhost too) on the local
filesystem, and sent it in background.

However there is no limit for this storage, and if the remote is
unavailable (or some other error), these pending blocks may take
significant space, and this is not always desired behaviour.

Add new Distributed setting - bytes_to_throw_insert, that will set the
limit for how much pending bytes is allowed, if the limit will be
reached an exception will be throw.

By default was set to 0, to avoid surprises.
