os/bluestore: default bluestore_block_size 1T -> 100G

This makes vstart *way* faster.  This option is only really relevant
for dev test environments.  We bumped it up back in dbdd1d9b6ec286982b5e86d4c51f831cc16afc12
from 10G just to make ENOSPC less common in dev/test.  Let's see if 100G
is a better balance.
