ospfd: Max multipath config support
Description:
OSPF does not have an option to control the maximum multiple
equal cost paths to reach a destination/route(ECMP).
Currently, it is using the system specific max multiple paths.
But Somtimes, It requires to control the multiple paths from ospf.
This cli helps to configure the max number multiple paths in ospf.
