Support for Oracle Cloud Vault

[herberthnilsen]

Hi,

I work at Oracle and a customer is using this component, I clone your repo and make an update to support Oracle Cloud Vault

please, check it out and when possible include this directly on your repo.

I don't know Go Lang, so I don't create the files to test the solution and I comment a lot of lint that was on Makefile just to build the container,

The solution is working to Oracle Cloud Vault, but don't have automated test files.

Checkout on my git
