Botond Dénes 341c29bd74 Merge '[Backport 6.0] storage_service: Fix race between tablet split and stats retrieval' from Raphael "Raph" Carvalho
Retrieval of tablet stats must be serialized with mutation to token metadata, as the former requires tablet id stability.
If tablet split is finalized while retrieving stats, the saved erm, used by all shards, can have a lower tablet count than the one in a particular shard, causing an abort as tablet map requires that any id feeded into it is lower than its current tablet count.

Fixes https://github.com/scylladb/scylladb/issues/18085.
