Support caching configuration

**Description**
Currently config lacks proper retry support.

**Proposed solution**
Add configurable retry with sensible defaults.

**Priority**: Low/Medium

Reconcile the title's caching configuration with the description's request for configurable retry support before starting. Locate the configuration implementation and determine the sensible defaults and expected retry behavior; done means the behavior is configurable and the defaults are documented or tested.
