Currently empty storage_groups are allocated for tablets that are
not on this shard.
Allocate storage groups dynamically, i.e.:
- on table creation allocate only storage groups that are on this
shard;
- allocate a storage group for tablet that is moved to this shard;
- deallocate storage group for tablet that is cleaned up.
Stop compaction group before it's deallocated.
Add a flag to table::cleanup_tablet deciding whether to deallocate
sgs and use it in commitlog tests.
before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.
in this change, we include `fmt/ranges.h` and/or `fmt/std.h`
for formatting the container types, like vector, map
optional and variant using {fmt} instead of the homebrew
formatter based on operator<<.
with this change, the changes adding fmt::formatter and
the changes using ostream formatter explicitly, we are
allowed to drop `FMT_DEPRECATED_OSTREAM` macro.
