Add support for variables that contain dashes

Currently, if a variable (or one of the child properties of a variable) in config.yaml contains a dash symbol, the deployment automatically fails. It would be very useful to at least allow child properties to contain dashes, which are natively supported by the yaml format.

Use case: I’m building a template that would have different variable values based on region name, and I would have to remove the dash symbol from the region variable that comes from the deployment pipeline.

Error example:

ERROR:k8s_handle:RuntimeError: Variable names should never include dashes, check your vars, please: us-central1, us-east1

why this limitation appeared

AFAIK, if you put something like {{ some-variable-name }} in Jinja2 template, you will receive a very unclear error message. So this limitation was added to prevent confusing error messages.
