hosts/dredd(cirrus): Trade reliability for performance

André Breda requested to merge ist189409/nixrnl:ist189409-master-patch-34522 into master

Description of changes

The NFS Cirrus mount is meant to be a best-effort performant shared-storage option when using the cluster. Thus, it makes sense to allow the NFS server to immediately acknowledge writes even if they weren't yet sync-ed to physical media. Concretely, this means using the async option in the server's exports (rather than sync).

Context: I am currently patiently waiting for many small files to be copied from a lab PC's disk to the NFS mount.
