The latter is pretty popular test/lib header that disseminates the
former one over whole lot of unit tests. The former, in turn, naturally
includes sstables.hh thus making tons of unrelated tests depend on
sstables class unused by them.
However, simple removal doesn't work, becase of local_shard_only bool
class definition in sstable_utils.hh used in simple_schema.hh. This
thing, in turn, is used in keys making helpers that don't belong to
sstable utils, so these are moved into simple_schema as well.
When done, this affects the mutation_source_test.hh, which needs the
local_shard_only bool class (and helps spreading the sstables.hh
throughout more unrelated tests) and a bunch of .cc test sources that
used sstable_utils.hh to indirectly include various headers of their
demand.
After patching, sstables.hh touches 2x times less tests. As a side
effect the sstables_manager.hh also becomes 2x times less dependent
on by tests.
