a813f5996e Fix converting types for UNION queries (may produce LOGICAL_ERROR) 
CI founds [1]:

The problem is that subqueries returns different headers:
- first query  -- x, y
- second query -- y, x

v2: Make order of columns strict only for UNION

Fix various clang-tidy warnings 
When I tried to add cool new clang-tidy 14 warnings, I noticed that the
current clang-tidy settings already produce a ton of warnings. This
commit addresses many of these. Almost all of them were non-critical,
i.e. C vs. C++ style casts.

Activate clang-tidy warning "readability-container-contains" 
This check suggests replacing <Container>.count() by
<Container>.contains() which is more speaking and in case of
multimaps/multisets also faster.

97acf190ed Replace old _shard_num implementation with shardNum() function 
_shard_num via constant identifier (from #7624) has too much issues,
take a look at #16947 for example.

shardNum() function (from #27020) should works better.

This changes the behaviour of _shard_num slightly, now it returns nested
shard number in case of nested distributed tables (Distributed over
Distributed), but this should be minor.

v2: Rewrite _shard_num to shardNum() in TreeRewriter
