* Replace SHA256 task hash with MD5
Add object hash to object table (always overwrites)
Support for table operations that span multiple asynchronous Redis
commands

Fix for object_table_add
Revert "Replace SHA256 task hash with MD5"
This reverts commit e599de473c8dad9189ccb0600429534b469b76a2.
Revert to sha256
