glusterd: Introduce volume op-versions
Each volume is now associated with two op-versions, * op_version - the op-version of the highest op-versioned feature enabled * client_op_version - the op-version of the highest op-versioned feature enabled which affects the clients only. These two op-versions are generated dynamically and kept updated during runtime. Glusterd now uses the respective volumes' client-op-version during getspec requests. To achieve the above a new field in the vme table is introduced, client_option, this boolean field tells if the option is a client side option.
