[LU-18986] Target registration to handle large amount of NIDs

Description

For upcoming features like multi-tenancy, target registration protocol have to handle large amount of NIDs passed to MGS, e.g. with 128 vlans and 4 interfaces on each that requires 512 NIDs to be passed.

Current limit is about 37 NIDs only, that is how many can fit in request buffer when NIDs are passed as inline mti_nidlist[] buffer in struct mgs_target_info. 

Main idea is to use bulk protocol when amount of NIDs is big and stick with inline buffer when NIDs fits in it.
