sstables: add ability to write and parse optionals
...
(that is, instances of `std::optional`).
The ME sstable format includes optional originating host id in stats
metadata. We know how to write and parse uuids, but not how to write
and parse optionals.
The format is (used by C* in this case, and also happens to be
consistent with how booleans are serialized): first a boolean
indicating whether the contents are present (0 or 1, as a byte), then
the contents (if any).
