loop: rename setparam command to setrule

As we add more paramters to the liqudity manager, it will become more
difficult to include them in a single cli endpoint with rules. This
commit renames the existing setparam command (which is only used for
rules at present), so that we can have a dedicated paramters cli
command for all the new values we are adding.
