Raphael S. Carvalho 3d9aa9d49e compaction: Reduce twcs off-strategy space overhead to 10% of free space
TWCS off-strategy suffers with 100% space overhead, so a big TWCS table
can cause scylla to run out of disk space during node ops.

To not penalize TWCS tables, that take a small percentage of disk,
with increased write ampl, TWCS off-strategy will be restricted to
10% of free disk space. Then small tables can still compact all
disjoint sstables in a single round.

Fixes #16514.
