[one-users] ONE + Gluster : deployment incomplete

[Javier Fontan]

These lines come by default in oned.conf [1]. I've also checked that
the CentOS package installs the conf file with those lines.

Your template for this conf file [2] seems to be done for an older
version and lacks those two lines.

Cheers
