Here is a concise summary of the pull request changes:

Summary: This pull request optimizes token handling in the kubelet package by introducing changes to minimize os.File reads, retry token retrieval on expiration, and refactor test cases.

Key Modifications:

1. In-memory storage of kubelet token to reduce file reads.
2. Token retrieval retry on expiration.
3. Removal of unused context variable.
4. Refactored httpGet function with new path parameter.
5. Updated ListPods function to call modified httpGet with saPath and podURL arguments.

Impact: These changes may affect the package's external interface and behavior. The introduction of a new global variable bearerToken and modified function signatures (e.g., httpGet) may require adjustments in dependent components.

Suggestions:

• Consider adding unit tests to ensure the new token retrieval logic and retry mechanism work as expected.
• Review the impact of the bearerToken global variable on the package's overall architecture and potential thread-safety concerns.
• Document the changes to the httpGet function and its new behavior to ensure clear understanding for future maintainers.
