Enable s3fs on secondary DC

[Daniele Dario]

Hi samba team,
I'm looking for the right way to enable s3fs on secondary my DC.

First DC (kdc01) is samba4 Version 4.0.0alpha21-GIT-7b55ec2 provisioned
with bind DLZ backend for DNS.

Secondary DC (kdc02) is samba4 Version 4.0.0alpha21-GIT-45082a8 joined
to the domain provisioned on kdc01.

On samba wiki I've found instructions to enable s3fs during provision
(--use-s3fs) but nothing for upgrades of samba or secondary DCs.

Thanks,
Daniele.
