cassini-[distro,bsp,docs]: Add `wait-online.sh` script to Cassini
requested to merge vikas.katariya1/meta-cassini:topics/CAS-75/AMPLATFORMS-3052-part-3 into nanbield-dev
Due to limitations of the Corstone-1000 platform, wait-online.sh
script can be included as part of Cassini base image instead of
Cassini test image only. This tool will be beneficial to the user
if the networking needs to be restarted.
