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.

Lock MEMORY_LIMIT_EXCEEDED error from tryLogCurrentException()
...
This will avoid hiding some exceptions in logs, when the server is under
high memory pressure (i.e. when any new allocation will lead to
MEMORY_LIMIT_EXCEEDED error).
This became more relevent after all memory allocations was tracked with
MemoryTracker, by falling back to total_memory_tracking, in #16121
