Make table manager retention options configurable in helm chart values (#9647)

**What this PR does / why we need it**:

Configuration options for table manager retention are hard-coded in the
helm chart values at the moment so that it's not possible to enable
retention deletes.

**Which issue(s) this PR fixes**:
Fixes #8676
