MT#9249 Add boot option ngcpfillcache & stop changing hosts/interfaces on Carrier

Also, we did s/RETRIEVE_MGMT_CONFIG/CARRIER_EDITION/g because /etc/hosts
and /etc/network/interfaces are fully configured for Carrier by ngcp-installer.
So, no need to touch them for Carrier at all now
(see commits to installer.git through this ticket).
