prepare 1.0.0 release

[LaunchDarklyReleaseBot]

[1.0.0] - 2022-12-07

The 1.0.0 release of this SDK supports LaunchDarkly's new custom contexts feature.

Contexts are an evolution of a previously-existing concept, "users".

Contexts let you create targeting rules for feature flags based on a variety of different information, including attributes pertaining to users, organizations, devices, and more.

You can also combine contexts to create "multi-contexts".

This feature is only available to members of LaunchDarkly's Early Access Program (EAP).

If you're in the EAP, you can use contexts by updating your SDK to the latest version and, if applicable, updating your Relay Proxy.

Outdated SDK versions do not support contexts, and will cause unpredictable flag evaluation behavior.

If you are not in the EAP and would like to use this release, then:

• only use single contexts of kind "user".

If you are not in the EAP and you create non-user contexts, the context data will be sent to LaunchDarkly, but any data not related to the user object will be ignored.

For information on how to upgrade from the previous version, please read the Rust SDK v1 implementation guide.
