Create a command to clear JWK Cache/Publickeys

We are experiencing an issue with zOS Connect/Liberty where the JSON Web Keys (JWKs) cached from a specific jwkEndpointUrl are not being refreshed unless there is a server recycle. This issue arises because our JSON Web Tokens (JWTs) do not use a new “kid” value when the keys are updated. As a result, Liberty continues to use the old, cached keys for validation, leading to authentication or authorization failures. To address this issue, we are requesting a command to manually clear the JWK cache in Liberty since we do not change our publickey/kid due to security reasons. This command would allow us to force Liberty to discard the old keys and fetch the new ones from the jwkEndpointUrl, ensuring that the system is always using the correct keys for validation. Some zOS Connect cache clearing commands do exist, just not for this JWK publickey. There is already a Liberty command to clear the authentication cache: https://www.ibm.com/docs/en/was-liberty/zos?topic=zos-modify-commands, and this request is for a similar capability. The primary beneficiaries of this command would be system administrators managing Liberty, as it provides them with greater control and flexibility in managing system security and performance. This enhancement would significantly improve our ability to manage system security and performance, and streamline troubleshooting processes related to JWT validation.
