The helper methods for sanitize/underscore/camelize were recently updated to cache values in static maps. This would lead to a memory leak in hosted environments as the maps had no cleanup/expiry.
This moves those cached entries to Caffeine caches with expiry based on last access to allow the edge-case performance improvement gains on very large documents, without the memory leak in hosted or embedded environments.

PR checklist
-
Read the contribution guidelines. -
If contributing template-only or documentation-only changes which will change sample output, build the project before. -
Run the shell script(s) under ./bin/(or Windows batch scripts under.\bin\windows) to update Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit, and these must match the expectations made by your contribution. You only need to run./bin/{LANG}-petstore.sh,./bin/openapi3/{LANG}-petstore.shif updating the code or mustache templates for a language ({LANG}) (e.g. php, ruby, python, etc). -
File the PR against the correct branch: master,4.3.x,5.0.x. Default:master. -
Copy the technical committee to review the pull request if your PR is targeting a particular programming language.
