Lakshmi Narayanan Sreethar e0189ccac5 sstable_directory: do not load remote sstables in process_descriptor
The sstable loader relied on the generation id to provide an efficient
hint about the shard that owns an sstable. But, this hint was rendered
ineffective with the introduction of UUID generation, as the shard id
was no longer embedded in the generation id. This also became suboptimal
with the introduction of tablets. Commit 0c77f77 addressed this issue by
reading the minimum from disk to determine sstable ownership but this
improvement was lost with commit 63f1969, which optimistically assumed
that hints would work most of the time, which isn't true.

This commit restores that change - shard id of a table is deduced by
reading minially from disk and then the sstable is fully loaded only if
it belongs to the local shard. This patch also adds a testcase to verify
that the sstable are loaded only in their respective shards.

Fixes #21015
