Add allow_preview parameter to azure_rm_aksversion_info

[mkirkeng-leukeleu]

SUMMARY

Add boolean allow_preview parameter to azure_rm_aksversion_info to allow users get only versions which are not in preview.

When set to true all orchestrator versions, in preview or not, are returned. When set to false only orchestrator versions with a missing or False value for is_preview are returned.

The default for allow_preview should be set to true to maintain current behavior.

ADDITIONAL INFORMATION

We currently use azure_rm_aksversion_info to use the newest currently supported versions when creating kubernetes services, but when preview versions are released we don't yet want to use those.

    azure.azcollection.azure_rm_aksversion_info:
      location: "SOME LOCATION"
      allow_preview: false
