### What changes were proposed in this pull request?
<!--
Please clarify what changes you are proposing. The purpose of this section is to outline the changes and how this PR fixes the issue.
If possible, please consider writing useful notes for better and faster reviews in your PR. See the examples below.
1. If you refactor some codes with changing classes, showing the class hierarchy will help reviewers.

3. If there is design documentation, please add the link.
4. If there is a discussion in the mailing list, please add the link.
-->
Convert `CaseInsensitiveStringMap#logger` to static, it's safe since the `org.slf4j.Logger` is thread-safe.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
To improve performance.
The overhead of `LoggerFactory.getLogger(CaseInsensitiveStringMap.class)` is non-negligible.
I always see this when I refresh the page "Thread dump for executor".
