This patch makes the functions in scylla-blocktune available as a
library for other scripts - namely scylla_io_setup.
The filename, scylla-blocktune, is not the most convenient thing to call
from python so instead of just wrapping it in the usual test for
__main__ I am just splitting the file into two.
Another option would be to patch all callers to call
scylla_blocktune.py, but because we are usually not using extensions in
scripts that are meant to be called directly I decided for the split.
