v5.0.0

• (Breaking) Modify client initialization to allow jitter configuration on refresh/background refresh intervals. May break code when parameters to UnleashClient are not used as keyword arguments. Thanks @dryobates and @jstolarski!
• (Major) If client is already initialized, calling initialize_client() again won't re-run initialization.
• (Minor) Support HTTP 304 on /client/feature endpoint.
• (Minor) Rename master to main.
• (Documentation) Document running UnleashClient in uWSGI. Thanks @sighphyre!
