krbd, kcephfs: trash osd primary-affinity

libceph.ko support is in testing and should be in 3.15.  This commit
effectively reverts commit 66ffaa65657b ("kcephfs, krbd: do not thrash

multimds: fuse_default_permissions = 0 for kernel build test

This can reduce the test time becuase it avoids sending getattr
request whenever the kernel checks inode permission.

Merge pull request #21 from ceph/wip-thrash-affinity

krbd, kcephfs: trash osd primary-affinity
multimds: test ceph-fuse and kclient

Add client as a variable on the basic collection.  Move the other stuff
(libcephfs plus a weird restart test) to libcephfs collection.
