This PR implements an object layer which combines input erasure sets of XL layers into a unified namespace. This object layer extends the existing erasure coded implementation, it is assumed in this design that providing > 16 disks is a static configuration as well i.e if you started the setup with 32 disks with 4 sets 8 disks per pack then you would need to provide 4 sets always. Some design details and restrictions: - Objects are distributed using consistent ordering to a unique erasure coded layer. - Each pack has its own dsync so locks are synchronized properly at pack (erasure layer). - Each pack still has a maximum of 16 disks requirement, you can start with multiple such sets statically. - Static sets set of disks and cannot be changed, there is no elastic expansion allowed. - Static sets set of disks and cannot be changed, there is no elastic removal allowed. - ListObjects() across sets can be noticeably slower since List happens on all servers, and is merged at this sets layer. Fixes #5465 Fixes #5464 Fixes #5461 Fixes #5460 Fixes #5459 Fixes #5458 Fixes #5460 Fixes #5488 Fixes #5489 Fixes #5497 Fixes #5496
