Remove dependencies with "bad" license. #1820
Description
Towards: cncf/sandbox#211
All third-party dependencies for external-secrets must comply with CNCF licensing policies - See Allowed third party license policy | cncf/foundation. I've opened cncf/foundation#485 to request exception for the hashicorp libs.
