1. gcloud container clusters get-credentials before using kubectl.
2. introducing properties-local.mk
3. The properties-local.mk is "empty" with check that "project" and "region" are defined by the developer.

Thanks for this @anderskristian!

I'll review this as soon as I have some time (hopefully later this week) 💪

@falko - Can you review this when you have a chance?

This moves custom configurations (such as custom region, machine type, cluster name, dns name, etc) into .mk files inside a config directory.

Please let me know what you think? If you give the 👍 , then I'll refactor azure and aws to match.

[upgradingdave]

Refactored aws tls profile to use config directory.

Still need to refactore other aws profiles as well as azure profiles.

[anderskristian]

I have added .ignore file + improved the Google README.md file with a "sub menu"
I really like the standardisation that @upgradingdave added above.
