Update Cassandra to write history tasks to new columns

[Shaddoll]

What changed?

• Refactored persistence layer to separate the task serialization logic into a new component
• Updated Cassandra plugin to encode history tasks into thrift blobs and write them into new columns introduced in Refactor peristence layer to support inserting history tasks of new categories #6671
• Removed some deprecated data types and unused data field from persistence task types

Why?
This is a followup change of #6671. We want to migrate Cassandra's transfer, timer, replication task data from typed columns to encoded blob columns introduced in that PR. After this change Cassandra will be in "dual write" mode.
Another followup PR will be created to allow specifying which column we read data from. Currently, we still read history tasks from the original columns as before.
No backfill is required for transfer tasks and replication tasks because old data not inserted with "dual write" mode will be gone soon after the deployment of this PR. A backfill process is required for timer tasks.

How did you test it?
Unit test, manual tests in dev2 environment, persistence test will be created in the followup PR that enables migration on reading tasks

Potential risks
tasks not encoded correctly (no impact production until we enable migration on reading tasks), history task processing might be broken
