This commit is only backporting an adapting to implement per node locking API Before this commit, each disk has its own locker API that needs to be called when locking/unlock resources. This has a performance implication if one deployment has many disks. This PR changes locking calls to use one single endpoint per server instead of an endpoint for each disk. Meaning, if you want to lock a resource, lock calls will be sent per server and not per node.
