v0.4.1

Added

• flexkube_containers configuration can have now env field specified to set environment variables
  for containers.
• Added configuration for running E2E and local tests.

Changed

• libflexkube has been updated to v0.4.3.
• Migrated to Terraform SDK v2.
• flexkube_pki resource has been rewritten to follow the patterns from other resources. It should no longer report
  inconsistent plan issues and should no longer show ambiguous changes.
• All resources will now produce less verbose diff when running terraform plan and will show that fields will have
  new values computed instead. That should greatly reduce number of issues with inconsistent plan, at the cost of
  changes visibility.

Fixed

• flexkube_helm_release now validates fields values and kubeconfig to make sure they contain valid YAML
  formatted content, so it does not corrupt the Terraform state, which requires manual interaction to recover from.
• Added missing documentation to flexkube_containers resource for host block.
• Adding and removing controller nodes should now work without interruption. Previously, it has been broken because of a bug
  in libflexkube and flexkube_pki and flexkube_etcd_cluster resources complaining about the inconsistent plan.
