Just wondering why would master nodes want to keep the index directories around?

…ata only node If a folder for an index was created that folder is never deleted from that node unless the index is deleted. Data only nodes therefore can have empty folders for indices that they do not even have shards for. This commit makes sure empty folders are cleaned up after all shards have moved away from a data only node. The behavior is unchanged for master eligible nodes. closes #9985

in this case isn't the exception wrong? I mean shouldn't we just skip it in that case?

I changed the
testShardActiveElseWheretest to sometimes use data only nodes, not sure if this is useful. Also I added the check forclusterState.metaData().hasIndex(indexName)inIndicesService.deleteIndexStoreagain. Did not come up with a better way to solve this.
