Update provider and examples to cope with updated/changed plans

[jixt]

Problem

Using for example the kubernetes example, the deployment fails because the plan 'development' doesn't exist anymore. The default values don't work anymore.

Solution

Update the provider and also examples in order to work with current plans.

Sorry for the delayed response! This should have been fixed in v0.1.0, but did not confirm by testing yet 👀
