Add use_analyzer_for_mutations config to override analyzer choice for mutations
...
When set in the server config, this option overrides the session setting
`allow_experimental_analyzer` for `MutationsInterpreter`. Absent (default)
means the session setting is used.
The override is parsed once per config reload in `Server.cpp` and stored as
a tri-state atomic on the shared context, so each mutation only pays an
atomic load instead of re-reading the config.

Add a server setting to allow new() throw MEMORY_LIMIT_EXCEEDED
...
Add a server setting (`min_allocation_size_to_throw_on_memory_limit`) to
allow any allocation to throw `MEMORY_LIMIT_EXCEEDED`, this should help
with preventing OOMs
Right now, any `new` cannot throw, this is due exception safety issues,
and only explicitly marked can throw `MEMORY_LIMIT_EXCEEDED`.
But this can lead to real OOMs, i.e. when kernel will kill
clickhouse-server, even though we are trying hard to track memory
properly.
Add a server setting `min_allocation_size_to_throw_on_memory_limit`
(UInt64 bytes, default 0). When non-zero, the throwing `operator new`
variants are allowed to raise `MEMORY_LIMIT_EXCEEDED`. _The assumption
is that code with big enough allocations does not exception safety
issues._
Note, places that allows (Allocator)/never allows (malloc)
`MEMORY_LIMIT_EXCEEDED` before are not affected.
