205ebc7cff Tune idle_connection_timeout to avoid reconnects 
There may be 1 hour between two different distributed queries in tests
(see [1] and [2]), if this will happen then the connection may be closed
already due to idle_connection_timeout.

  [1]: https://clickhouse-test-reports.s3.yandex.net/21432/572d5862961ffda88125679e3a5ea684c316b223/functional_stateless_tests_(debug).html#fail1

Let's tune it to avoid such issues and override other settings in tests.

Another option is to execute SYSTEM RELOAD CONFIG before each test...

7794ac66d4 Fix flaky tests with distributed queries 
There was few attempts to fix this [1] and [2], but it still pops up
sometimes, for example here [3].

  [1]: 009f57fc2f / #11211
  [2]: cdb6bed8b9 / #14198
  [3]: https://clickhouse-test-reports.s3.yandex.net/21318/38be9ff43ac4c46ce6e803fc125d910bde1d4c71/functional_stateless_tests_(release,_databasereplicated).html#fail1

Let's use more generic approach, and do not hide any errors (and see
does increasing timeout will be enough).

f96892d45c Speed up network partition test 
REJECT rather than DROP packets in network partition test.  This test
was already very slow and could get slower with the newly added
reconnection logic.

641b1b249e Attempt to reconnect to MySQL 
For MaterializeMySQL databases, attempt to reconnect if the connection
to MySQL is lost.  The existing setting
`max_wait_time_when_mysql_unavailable` is used to control how often we
attempt to reconnect.  This setting can now be set to a negative value
to disable reconnects.

e6711675a1 Make handling of unavailable MySQL consistent 
If MySQL was unavailable when loading an existing database on startup,
we would previously load the database, fail to start synchronization,
but allow queries to the database.  Change this to only allow queries
if the `allows_queries_when_mysql_lost` setting is on, so that the
behavior is consistent with what happens if the connection to MySQL is
lost while ClickHouse is running.

Also retry connection to MySQL if MySQL is unavailable when ClickHouse
is started (we would previously reconnect only if the connection was
lost during the initial dump of existing data).

e7948819f9 Fix ParsingException::displayText() 
Before it was silently try-catched for messages with additional {}, and
it is very easy to trigger, i.e.:

    SELECT toDateTime(format('{}-{}-01 00:00:00', '2021', '1'))

Will print:

    Code: 41. DB::Exception: Received from localhost:9000. DB::Exception: Cannot parse datetime 2021-1-01 00:00:00{}: Cannot parse DateTime from String: while executing 'FUNCTION toDateTime(format('{}-{}-01 00:00:00', '2021', '1') :: 3) -> toDateTime(format('{}-{}-01 00:00:00', '2021', '1')) DateTime : 2'.

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

lock for metrics, so it is fine.
