Statsig

Improved the ID list sync'ing logic so that it's using a new endpoint and can scale better with larger lists

Added two parameters to `StatsigOptions`:

`bootstrap_values: str = null`

a string that represents all rules for all feature gates, dynamic configs and experiments. It can be provided to bootstrap the Statsig server SDK at initialization in case your server runs into network issue or Statsig server is down temporarily.

`rules_updated_callback: typing.Callable = None,`

a callback function that's called whenever we have an update for the rules; it's called with a logical timestamp and a JSON string (used as is for bootstrapValues mentioned above). Note that as of right now, this will be called from a background thread that the SDK uses to update config values.

Fixes and issue where the ID list background thread updater threw an exception when trying to remove IDs from a list when the ID already did not exist

The shutdown API had an issue where the background threads were waiting to be joined in shutdown in `localMode` per 4

The override APIs were improperly preferring global to user level settings, so if you had a user level override and a global override, you would always get the global override. This made it impossible to override a gate to true for all but one user

Testing utility functions

`override_gate(gate:str, value:bool, user_id:str = None)` - overrides a gate to the given value. If a user_id is not provided, all gate checks will return this value. If a specific user_id is passed, the override only applies to that given user_id

`override_config` and `override_experiment` function similarly, but for DynamicConfigs and Experiments

`StatsigOptions.local_mode`- local mode disables network access, so the SDK will only return default values and never hit statsig servers. Useful for unit testing

`evaluate_all(user)` - given a user, evaluates all gates/configs/experiments in the project and returns a dictionary with the results. Useful for reproducing an issue and determining which values a given user has

ID Lists

Adds python SDK support for ID lists: https://docs.statsig.com/segments/add-id-list

Enforces a minimum timeout on network requests from the SDK, and makes that timeout configurable via StatsigOptions
