feat(ai-proxy): add client token; add rate-limit filter (#6045)

* add api for client-token

* support check client token

* polish token create: add metadata; support createOrGet

* remove useless configs: providers/platforms

* fulfill audit from client token

* add rate-limit filter for client token

* fix golangci-lint

* comment out CODE-TEST cmp temporarily
