This commit adds the dns category to the --resolve command line option,
because it can be interpreted as both: a low-level connection option and
an option related to the resolving of a hostname.
It is also not common for dns options to belong to the connection
category and vice versa. --ipv4 and --ipv6 are both good examples.
Closes #9229
