Investigate whether it's possible to restrict users from collections via SPARCd

**IMPORTANT**
This issue is to investigate if it's possible to change collection access permissions in Minio/S3/etc through SPARCd

**Is your feature request related to a problem? Please describe.**
Right now users need to log onto Minio and be familiar with the security schema to change access permissions to collections - currently all collections are public

**Describe the solution you'd like**
Change how permissions are handled in SPARCd to automate them in Minio

**Describe alternatives you've considered**
