min.io support

[drernie]

The Boto APIs used for S3 should work with Minio, but we need:

• an environment to test against
• provide configuration documentation

Compare the NextFlow Documentation:

S3-compatible storage

To use S3-compatible object storage such as Ceph or Minio specify the endpoint of your storage provider and enable the S3 path style access in your Nextflow configuration as shown below:

aws {
    accessKey = '<Your access key>'
    secretKey = '<Your secret key>'
    client {
        endpoint = '<Your storage endpoint URL>'
        s3PathStyleAccess = true
    }
}
