Kefu Chai	c980bd54ad	utils: specialize fmt::formatter<optional<>> ... this is a part of a series to migrating from `operator<<(ostream&, ..)` based formatting to fmtlib based formatting. the goal here is to enable fmtlib to print `optional<T>` without the help of `operator<<()`. this change also enables us to ditch more `operator<<()`s in future. as we are relying on `operator<<(ostream&, const optional<T>&)` for printing instances of `optional<T>`, and `operator<<(ostream&, const optional<T>&)` in turn uses the `operator<<(ostream&, const T&)`. so, the new specialization of `fmt::formatter<optional<>>` will remove yet another caller of these operators.

Kefu Chai	93fa70069c	utils: to_string: move join to namespace utils ... `join` can easily be confused with boost::algorithm::join so make it more visible that we're using scylla's utils implementation. Also, move `struct print_with_comma` to utils::internal. Signed-off-by: Benny Halevy <bhalevy@scylladb.com>	2023-03-16 20:34:18 +08:00
