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

concurrency
Use Redis GETSET instead of transactions and Python frontend code for object hashing

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