Title: Try to stop SOLr shards gracefully before force killing them.

On distributed file systems SOLr may produce lockfiles to control access to the shard files. These are not removed if you kill them with "kill -9". A normall kill with 1s delay is sufficient to clean up the lockfiles on CEDA's index node.
