[Pacemaker] colocation and ordering for groups/clones/instances

[gustavo panizzo <gfa>]

i fix my ordering problems using fully explicit order "chains"  

colocation col_db0005 +inf: HASI ora-bkp vgoradb vgoralog db0005-storage db0005-db db0005-ip
order ord_db0005 +inf: HASI ora-bkp vgoradb vgoralog db0005-storage db0005-db db0005-ip

it really works, crm configure verify give OK. 
but i cannot found any reference to this on the documentaion, it is supported? 
will it be supported in the future?

thanks
