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.
