swagger(scylla): remove endpoint getting replace_address_first_boot c…

…onfig value

Since scylladb/scylladb@1577aa8 (5.2), the replace_address and replace_address_first_boot options are deprecated and their usage is discouraged, and warned about (when used).
Instead, the user should use the replace_node_first_boot which states the replaced node's host_id rather than its ip address.
