[PATCH] clone: send server options when using protocol v2




Commit 5e3548ef16 ("fetch: send server options when using protocol v2",
2018-04-24) taught "fetch" the ability to send server options when using
protocol v2, but not "clone". This ability is triggered by "-o" or
"--server-option".

Teach "clone" the same ability, except that because "clone" already
has "-o" for another parameter, teach "clone" only to receive
"--server-option".
