This PR improves Train lazy checkpointing with NFS setups. Previously, the logic to determine whether lazy checkpointing should be used was dependent on whether the Train worker-actor was on the same node as the Trainable actor. The new logic instead has the Trainable actor drop a marker file in the Trial's directory. If a worker-actor can detect that file, it means it can access the same directory as the Trainable actor. This PR also fixes lazy checkpointing env var propagation. Signed-off-by: Antoni Baum <antoni.baum@protonmail.com> Signed-off-by: Edward Oakes <ed.nmi.oakes@gmail.com>
