rpc_commands_lib.py: make cluster size optional argument as
sometimes we only need to check if lvol store exists and not
care about details.
Test cases 600 and 601 fix: add missing delete_bdev() at the end,
add using get_lvol_stores to check if lvol store was created.
Test case 601 modified:
Change test case to check if creating a lvol store with cluster
size less than 8192 is disallowed.
Previous check for cluster size of 0 was incorrect as 0 is an
allowed value for that operation and results in setting default
cluster size.
