  - k8s: Make ONAP context default for kubectl

    This patch uses previously added alias for kubectl context switching in
    case it is needed as a template for other contexts as well.

    Issue-ID: SECCOM-235
    Change-Id: Ie92641ee3763a027cd74dd21bf4364a2d796eb1d

  - 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)

  - k8s: Add kubectl provisioners (downloading and setting up)

    Setting up kubectl depends on presence of K8s cluster post-deployment
    artifacts, hence it's disabled by default. Relevant information added to
    post-up message.

    This patch also removes unneeded curly braces from
    "tools/dublin/get_rke.sh" script.
