DAOS-18613 container: Add pool UUID to cont_op_in (#17921)#18209

Current cont_op_in types do not include a pool UUID field. An engine
receiving such a request has to obtain the pool UUID by looking up the
pool handle. If the handle is not cached locally, the engine is unable
to fetch the pool handle from the PS because it doesn't have the pool
UUID. Hence, we need to add a pool UUID field to a new version of
cont_op_in.
This patch introduces version 9 (v9) of the container RPC protocol:
- In v9, cont_op_v9_in includes the pool UUID field ci_pool.
- All requests using a cont_op_in type gets a v9 version.
- Engine-to-engine CONT_PROP_SET_BYLABEL is changed directly.
- cont_prop_set_v9_in no longer has cpsi_pool_uuid, for the new
cpsi_op.ci_pool has that.
- cont_tgt_query_in no longer contains the pool handle UUID. This
engine-to-engine request is changed directly.
- The v8 protocol remains unchanged.
- The v7 and earlier stuff is removed.
- Unnecessary opc and cont_proto_ver parameters are removed.
- Unnecessary ds_cont_op_handler_{v6,v7,v8} are removed.
