distributed_loader is replica-side thing, so it belongs in the
replica module ("distributed" refers to its ability to load
sstables in their correct shards). So move it to the replica
module.
The change exposes a dependency on the construction
order of static variables (which isn't defined), so we remove
the dependency in the first two patches.
Closes#9891
