Set nova disk cachemodes to file directsync
Set nova/libvirt disk cache modes to file directsync to bypass the
host page cache & prevent instance's kernel panic due to absent
/dev partition. Caching mode directsync effectively turns all guest
I/O operations into direct I/O operations on the host, which is the
NFS client (virtuals) or GlusterFS (baremetals).
Also return back to hwe kernel as a golden mean between GA & Edge ones.
