LU-2183 osp: cleanup osp-on-ost
With new quota design and FIDonOST introduced, a new connection
from OST/MDTn to MDT0 is required for sending quota and sequence
RPCs. This connection was implemented by adding a new special
osp device named osp-on-ost, which introduced complexity to osp
code, and many hacks of checking the osp device name in both
client and server side code.
In this patch, we removed the osp-on-ost, and introduced a new
device type lwp (Light Weight Proxy) to manage the light weight
connection established from OSTs/MDTs to MDT0.
