We make v2 client code a module go.etcd.io/etcd/client/v2. Pretty mechanical change that can be summarized as: mkdir client/v2 cd client/v2 && git mod init go.etcd.io/etcd/client/v2 git mv client/*.go client/v2/ find -name '*.go' | xargs sed -i --follow-symlinks 's|/v3/client["]|/client/v2\"|g' + fixing changelog, bom, go.mod etc.
