  - k8s: Remove hardcoded password for 'vagrant' user

    Password for 'vagrant' user is now passed through exported environmental
    variable.

    This patch also:

    * removes the assumption of having 'vagrant' user on cluster nodes (for
      future scripts reuse),
    * removes mixed string interpolation and passing shell variables,
    * replaces '~' with '$HOME' for proper substitiution.
