Provider CRDs

[jmendesky]

Overview

Providers are currently configured globally and their use cannot be restricted.
Introduce provider CRDs.

Tasks:

• Introduce cluster-wide namespace CRD following the current configuration
  • service accounts can be assumed to be managed outside (i.e. create is no longer needed)
  • can the service account configuration move inside the provider configuration?
  • should type be configured at operator installation time so that versions match? Alternatively, can type be replaced by providerImage?

  TODO

• Research and Implement a mechanism to create provider-specific resources for each provider CRD
  • templated
  • the lifecycle of provider resources should depend on the provider's lifecycle
• Remove default providers
