Add git remote set-branches 

Add ‘git remote set-branches’ for changing the list of tracked refs
for a remote repository with one "porcelain-level" command.  This
complements the longstanding ‘git remote add --track’ option.

The interface is based on the ‘git remote set-url’ subcommand.

   git remote set-branches base --add C
   git remote set-branches base A B D
   git remote set-branches base --delete D; # not implemented

'set-branches'::
Changes the list of branches tracked by the named remote.
This can be used to track a subset of the available remote branches
after the initial setup for a remote.
+
The named branches will be interpreted as if specified with the
`-t` option on the 'git remote add' command line.
+
With `--add`, instead of replacing the list of currently tracked
branches, adds to that list.
'set-url'::
Changes URL remote points to. Sets first URL remote points to matching
