Michal Rostecki 84e5e2894f aya-log: Unify IP format hints into one, repsesent it by `:i` token
Having separate format hints and tokens per IP address family is
unnecessary, since they are represented by different types and we handle
format hints for each type separately. So we can just have one format
hint.

Also, we should be consistent with the format strings grammar in
Rust[0]. The `type` token, which is mapped to formatting traits, usually
consists of one letter[1] (and optional `?` for `Debug` trait, but that
doesn't matter for us). It shouldn't consist of multiple letters. Our
`:ipv4` and `:ipv6` tokens were clearly breaking that convention, so we
should rather switch to something with one letter - hence `:i`.
