cmd/lncli: group Mission Control cmds into own category

To make the "Payments" category a bit less overloaded and to move the
Mission Control configuration commands away from the "root" category, we
create the new "Mission Control" category that we move the commands
into. We do this in a single commit so the next one where we move them
into the same file can be a pure code move without any additional
changes.
