internal: Add persistence support for sessions with defer (#4644)

## Description

- We're adding sessions support for defer. Deferred functions should be
able to use both manual and propagated sessions
- In this PR, we add piping so that meta.sessions can be travel from the
SDK's opcode -> persistence in Redis -> executor attaches it on to the
`deferred.schedule` event
- In later monorepo PRs, we'll add scylladb support
- EXE-2035
