Sean Barag de9ed3ef37 clone: allow configurable default for `-o`/`--origin`
While the default remote name of "origin" can be changed at clone-time
with `git clone`'s `--origin` option, it was previously not possible
to specify a default value for the name of that remote.  Add support for
a new `clone.defaultRemoteName` config, with the newly-created remote
name resolved in priority order:

1. (Highest priority) A remote name passed directly to `git clone -o`
2. A `clone.defaultRemoteName=new_name` in config `git clone -c`
3. A `clone.defaultRemoteName` value set in `/path/to/template/config`,
   where `--template=/path/to/template` is provided
4. A `clone.defaultRemoteName` value set in a non-template config file
5. The default value of `origin`
