Allow Helm chart deployer to take values from file

[bdelwood]

Is your feature request related to a problem? Please describe.

Being able to bootstrap helm charts with the cluster is a convenient feature. However, currently chart values must be specified in-line in the k0s.yaml or k0sctl.yaml file.

Describe the solution you'd like
It would be convenient to be able to use a chart values file rather than have to put the values using in-line yaml. This makes value file management and especially version control far easier.

A big ➕ for this. Inlining anything in yaml is always painfull and VERY error prone.
