Add greedy test for decode/reconstruct result solid

Once using erasure code scheme in storage system, we have to trust the
backend's result consistency from decode/reconstruct. Otherwise, the
storage system can be broken easily. To trust the result, this patch
adds greedy combination testing for decode/reconstruct for read-solomn
based backends.

Testing:
- decode result from any k fragments must be consistent with original
  data
- The Nth fragment reconstructed from other k fragments must be
  consistent with the encoded Nth fragment

With this patch, we can confirm the consistency, at least, the testing
spec defined at get_pyeclib_testspec() method, and if you want to test
either other parameters or backends, you can add the spec you want to
test.
