Jim Harris 1edd9bf3e4 blobfs: Add a lightweight filesystem built on the blobstore
This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.

Also included in this patch:

1) a shim for using SPDK bdevs as the backing store for
   SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
   with RocksDB
3) scripts for running a set of workloads and collecting
   profiling data with RocksDB and blobfs

See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.
