Add commands to set and get LRP options

This patch is adding two new commands:

* lrp_set_options(): To set the "options" column for a LRP
* lrp_get_options(): To get the values of the "options" column of a LRP

Since the code is pretty much the same as the equivalent command for LSP
this patch attempts to reuse the same command for both.
