it turns out we have `using namespace httpd;` in seastar's `request_parser.rl`, and we should not rely on this statement to expose the symbols in `seatar::httpd` to `seastar` namespace. in this change, * api/*.hh: all httpd symbols are referenced by `httpd::*` instead of being referenced as if they are in `seastar`. * api/*.cc: add `using namespace seastar::httpd`.
