Updated salt support and convenience methods for flag providers

[efahk]

• Bumps SDK out of beta to version 5.0.0
• Updating hash scheme with support for custom salts and salts per rollout group
• Adds a routine to get_all_variants that doesn't track exposure events per customer requests

GitHub Copilot Summary

This pull request introduces new methods for retrieving all feature flag variants for a user context, improves exposure event tracking flexibility, and refines hashing logic for flag assignment. It also enhances remote flag evaluation with asynchronous support and improves logging granularity. These changes collectively make feature flag evaluation and tracking more robust, flexible, and testable.

Feature flag variant retrieval and exposure event tracking

• Added get_all_variants methods to both LocalFeatureFlagsProvider and RemoteFeatureFlagsProvider for retrieving all feature flag variants for a given user context, with manual exposure event tracking options (track_exposure_event and atrack_exposure_event) for both sync and async usage. [1] [2] [3] [4] [5]
• Updated exposure event tracking logic to allow manual reporting and made latency reporting optional. [1] [2] [3]

Hashing logic improvements for flag assignment

• Refined variant and rollout assignment hashing logic to include an optional hash_salt for better control and testability, and updated test helpers to support this. [1] [2] [3] [4]

Remote feature flags API improvements

• Improved remote flag evaluation by supporting async variant retrieval (aget_variant), updating query parameter handling, and separating response parsing from flag lookup for better error handling and testability. [1] [2] [3] [4]

Logging and diagnostics

• Changed request timing logs from info to debug level for less noisy logs in production. [1] [2]

Version bump

• Bumped package version from 5.0.0b2 to 5.0.0 in mixpanel/__init__.py.
