   - Call `get_optimizely_config` to get a snapshot copy of project configuration static data.
   - It returns an `OptimizelyConfig` instance which includes a datafile revision number, all experiments, and feature flags mapped by their key values.
   - Added caching for `get_optimizely_config` - `OptimizelyConfig` object will be cached and reused for the lifetime of the datafile
