Allow configuration of S3 Blob Store

[ron1]

Nexus 3.12 introduces support for S3 blob stores. The Nexus Operator should consider supporting an S3 blob store via an ObjectBucketClaim offered by the lib-bucket-provisioner operator (see https://github.com/kube-object-storage/lib-bucket-provisioner) and its various implementation operators.

When implementing this feature, please make sure to support access key / secret key (ak/sk) rotation. For example on OpenShift there is a Cloud Credential Operator handling creation of AWS IAM users and access key rotation (by simply deleting the secret containing the ak/sk). So the Nexus Operator could monitor the secret used for the blobstore and update the blobstore configuration when the secret changes.

hey @patlachance! thanks for reaching out. Do you have knowledge of Go and Operators to help us there? I have very limited time to work on this and I don't know when I'll be available to implement it. :(

@ricardozanini unfortunately I don't have enough knowledge of Go or operators development in Go, at the moment. Maybe some day! Till then, I'll try to have some colleagues looking at this issue!
