UserStory[Security]: Generate password for minio from Vault

[Neha-Sinha2305]

Description

As of today we use user provided screts to access minio, however, going forward we would like to generate these secrets from Vault. The KV Secrets Engine feature could be made use of to achieve this.

Acceptance Criteria

1. Remove the hardcoded minio_access_key, minio_secret_key .
2. Generate on demand password with vault
3. Add tests
4. Add/update documentation

Questions

1. How should this be handled in the minio-client(mc)?
   -- Set output variable in minio and use that in mc

Discussion

1. Code in vagrant-hashistack to enable KV secret engine
