k8s: Silence package manager and make it noninteractive

This patch sets debconf frontend to noninteractive by including
additional field in the first stanza of configuration file. Its
placement has been chosen arbitrarily - both 'Config' and 'Templates'
fields "are required in this first stanza" [1].

It also makes symlinking script more generic.

[1] man 5 debconf.conf (provided by "debconf-doc" in Ubuntu)
