LU-10278 utils: allow to migrate without direct io
Using direct i/o to copy file contents during migration minimizes
cache interference, but may significatly reduce performance.
Introduce new option -D/--non-direct to lfs migrate/lfs_migrate that
leaves the tradeoff at the discretion of the caller.
