Python-SDK - 3.4.0

## [3.4.0] - January 27th, 2020

### New Features:
* Added a new API to get project configuration static data.
* Call `get_optimizely_config()` to get a snapshot 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.
* For details, refer to our documentation page: [https://docs.developers.optimizely.com/full-stack/docs/optimizelyconfig-python](https://docs.developers.optimizely.com/full-stack/docs/optimizelyconfig-python).
