Krishnan Parthasarathi 7d50361ca9 Move housekeeping before object layer initialization (#3001)
In a distributed setup that the server should not perform any operation
on the storage layer after it is exported via RPC. e.g, cleaning up of
temporary directories under .minio.sys/tmp may interfere with ongoing
PUT objects being served by the distributed setup.
