Remove env variable from s3 bucket job

Remove the TLS_OPTION env from helm-toolkit s3-bucket job. There
can be different option for tls connection, depending on whether
the rgw server is local or remote. This change allows the
create-s3-bucket script to customize its connection argument
which can be pulled from values.yaml.
