read-ahead/io-cache: turn off by default
We've found perf xlators io-cache and read-ahead not adding any performance improvement. At best read-ahead is redundant due to kernel read-ahead and at worst io-cache is degrading the performance for workloads that doesn't involve re-read. Given that VFS already have both these functionalities, this patch makes these two translators turned off by default for native fuse mounts. For non-native fuse mounts like gfapi (NFS-ganesha/samba) we can have these xlators on by having custom profiles.
