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. Change-Id: I51ab7d0ee71c214ff16b756cfee16e918738b6fd Signed-off-by: Michael Polenchuk <mpolenchuk@mirantis.com>
