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.

2d03d330bc Extended range of DateTime64 to years 1925 - 2238
The Year 1925 is a starting point because most of the timezones
switched to saner (mostly 15-minutes based) offsets somewhere
during 1924 or before. And that significantly simplifies implementation.

2238 is to simplify arithmetics for sanitizing LUT index access;
there are less than 0x1ffff days from 1925.

* Extended DateLUTImpl internal LUT to 0x1ffff items, some of which
  represent negative (pre-1970) time values.
  As a collateral benefit, Date now correctly supports dates up to 2149
  (instead of 2106).
* Added a new strong typedef ExtendedDayNum, which represents dates
  pre-1970 and post 2149.
* Functions that used to return DayNum now return ExtendedDayNum.
* Refactored DateLUTImpl to untie DayNum from the dual role of being
  a value and an index (due to negative time). Index is now a different
  type LUTIndex with explicit conversion functions from DatNum, time_t,
  and ExtendedDayNum.
* Updated DateLUTImpl to properly support values close to epoch start
  (1970-01-01 00:00), including negative ones.
* Reduced resolution of DateLUTImpl::Values::time_at_offset_change
  to multiple of 15-minutes to allow storing 64-bits of time_t in
  DateLUTImpl::Value while keeping same size.
* Minor performance updates to DateLUTImpl when building month LUT
  by skipping non-start-of-month days.
* Fixed extractTimeZoneFromFunctionArguments to work correctly
  with DateTime64.
* New unit-tests and stateless integration tests for both DateTime
  and DateTime64.

e6f1ce48fe Fix handling of TABLE_MAP_EVENT from MySQL
The MySQL replication code assumed that row update events would be
preceded by a single TABLE_MAP_EVENT.  However, if a single SQL
statement modifies rows in multiple tables, MySQL will first send
table map events for all involved tables, and then row update events.

Depending on circumstances, this could lead to an exception when the row
update was processed, the update could be incorrectly dropped, or the
update could be applied to the wrong table.

921518db0a CLICKHOUSE-606: query deduplication based on parts' UUID
* add the query data deduplication excluding duplicated parts in MergeTree family engines.

query deduplication is based on parts' UUID which should be enabled first with merge_tree setting
assign_part_uuids=1

allow_experimental_query_deduplication setting is to enable part deduplication, default ot false.

data part UUID is a mechanism of giving a data part a unique identifier.
Having UUID and deduplication mechanism provides a potential of moving parts
between shards preserving data consistency on a read path:
duplicated UUIDs will cause root executor to retry query against on of the replica explicitly
asking to exclude encountered duplicated fingerprints during a distributed query execution.

NOTE: this implementation don't provide any knobs to lock part and hence its UUID. Any mutations/merge will
update part's UUID.

* add _part_uuid virtual column, allowing to use UUIDs in predicates.
