2.10.0 — Sentry Python

Various fixes & improvements

Add client cert and key support to HttpTransport (#3258) by @grammy-jiang

Add cert_file and key_file to your sentry_sdk.init to use a custom client cert and key. Alternatively, the environment variables CLIENT_CERT_FILE and CLIENT_KEY_FILE can be used as well.
OpenAI: Lazy initialize tiktoken to avoid http at import time (#3287) by @colin-sentry
OpenAI, Langchain: Make tiktoken encoding name configurable + tiktoken usage opt-in (#3289) by @colin-sentry

Fixed a bug where having certain packages installed along the Sentry SDK caused an HTTP request to be made to OpenAI infrastructure when the Sentry SDK was initialized. The request was made when the tiktoken package and at least one of the openai or langchain packages were installed.

The request was fetching a tiktoken encoding in order to correctly measure token usage in some OpenAI and Langchain calls. This behavior is now opt-in. The choice of encoding to use was made configurable as well. To opt in, set the tiktoken_encoding_name parameter in the OpenAPI or Langchain integration.
```
sentry_sdk.init(
    integrations=[
        OpenAIIntegration(tiktoken_encoding_name="cl100k_base"),
        LangchainIntegration(tiktoken_encoding_name="cl100k_base"),
    ],
)
```
