storage_proxy works with vectors of inet_addresses for replica sets and for topology changes (pending endpoints, dead nodes). This patch introduces new names for these (without changing the underlying type - it's still std::vector<gms::inet_address>). This is so that the following patch, that changes those types to utils::small_vector, will be less noisy and highlight the real changes that take place.
