Optimize some functions to subcolumns

18e8f0eb5e Add ability to push down LIMIT for distributed queries
This way the remote nodes will not need to send all the rows, so this
will decrease network io and also this will make queries w/
optimize_aggregation_in_order=1/LIMIT X and w/o ORDER BY faster since it
initiator will not need to read all the rows, only first X (but note
that for this you need to your data to be sharded correctly or you may
get inaccurate results).

Note, that having lots of processing stages will increase the complexity
of interpreter (it is already not that clean and simple right now).

Although using separate QueryProcessingStage looks pretty natural.

Another option is to make WithMergeableStateAfterAggregation always, but
in this case you will not be able to disable only this optimization,
i.e. if there will be some issue with it.

v2: fix OFFSET
v3: convert 01814_distributed_push_down_limit test to .sh and add retries
v4: add test with OFFSET
v5: add new query stage into the bash completion
v6/tests: use LIMIT O,L syntax over LIMIT L OFFSET O since it is broken in ANTLR parser

v7/tests: set use_hedged_requests to 0, to avoid excessive log entries on retries

Projections
TODO (suggested by Nikolai)

1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies

3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)

Also need to figure out how prewhere works for projections, and
row_filter_policies.

6fba6f7ddd Disable min_bytes_to_use_mmap_io by default
Reading files using mmap() does not have any significant benefits over
plain read() [1].

  [1]: https://gist.github.com/azat/3d6c8d82bdd91e7a38d997fd6bcfd574

And not only it does not have significant benefits, it also has some
issues, due to max_server_memory_usage (default to 90% of available
RAM), since when you read files with mmap() eventually process RSS may
exceed max_server_memory_usage, and in this case any allocation will
fail (with "Memory limit exceeded (total)") error (yes kernel will
unload pages, but likely it will happens after queries will starting to
fail), like in this test [2].

  [2]: https://gist.github.com/azat/4813489828162e6c2ce131963c6a1acb

TL;DR;

Note that there was also an idea to take those mmap()'ed regions in
memory tracking (#23211), but there are some drawbacks (since accounting
mmap() is tricky, first of all you need to account only once per inode
for file and plus kernel can unload some pages and those memory will not
be used by the server anymore).

And as an adddition to #23211 there was #23212, that adds
max_bytes_to_use_mmap_io, but since mmap is not a subject for memory
accounting there is no need in it.

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.
