[ntuple,daos] Create wrappers around backend-specific structures

[glmiotto]

This Pull request introduces wrappers to obfuscate backend-specific implementation details, distancing the storage layer functionality in RPageStorageDaos from the concrete backend in RDaos and libdaos.

Changes or fixes:

• Wraps the dictionary that groups page requests by their co-locality keys (a type previously aliased as MultiObjectRWOperation_t) into a new wrapper class MultiObjectRWOperation. The class manages the insertion of new request akeys and associated IOVs into the dictionary and exposes begin and end iterators for it.
• Moves RDaosKey to the header file and aliases the concrete types of DistributionKey_t and AttributeKey_t, used by other structures in the backend.
• Introduce wrapper structure RDaosIov to obfuscate the libdaos-specific d_iov_t structure and d_iov_set() call from the storage layer for object stores.
• Hide DAOS error code resolution function (d_errstr) in GetDaosError().
• Directly use existing RDaosObject::ObjClassId wrapper structure around the default metadata class definition in the storage layer.

Checklist:

• [x] tested changes locally + DAOS delphi node
• [x] updated the docs (if necessary)

@glmiotto IIUC, this is to be reviewed as an enhancement over the DAOS backend (i.e., improving separation between RDaos and the RPage{Source,Sink}Daos). Comments coming soon.
