Ceph

Currently when you pass multiple yaml inputs to teuthology, they have to combine cleanly. e.g.

foo:
 - a
 - b

and

bar:
 - c
 - d

combine, but

tasks:
 - firstthis:
     key: value

and

tasks:
 - thenthis:
     foo: bar

do not. They could, though, provided the types are consistent (as above).

tasks:
 - ceph:
     a: b

and

tasks:
   key: value

should throw an exception.

The ability to combine just at the top level will be pretty useful.
