[PATCH v2 1/3] clone: update submodule.recurse in config when using --recurse-submodule

["Mahi Kolla via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Mahi Kolla <mahikolla@xxxxxxxxxx>

When running 'git clone --recurse-submodules', developers expect various other commands such as 'pull' and 'checkout' to also run recursively into submodules.The submitted code updates the 'submodule.recurse' config value to true when 'git clone' is run with the '--recurse-submodules' option.
