Subject: [PATCH] [release] 1.20.0 - Optimizations & persistent storage updates
 (#172)

Made optimizations to evaluation logic:
- Unmarshal spec defaultValue and rule returnValue on initialization
(rather than per evaluation)
- Remove unnecessary string conversion for layer assignment
- Replace array contains with map lookup
- Replace `Sprintf` with `strconv`

#### Impact
- Reduces layer evaluation for layers with partial allocation by about
50%
- Reduces general evaluation for dynamic configs, experiments, layers by
about 15%
---
- Refactored persistent storage interface to include experiment name to
solve for concurrent user evaluations across SDK instances
