Can it support bandwidth limit?

### Prerequisites - [X] I have written a descriptive issue title - [X] I have searched existing issues to ensure the feature has not already been requested ### 🚀 Feature Proposal Example ```js options = { maxBandwidth: '1M' // every request the max bandwidth must be < 1M/s globalMaxBandwidth: '10M' // all request the max bandwidth sum must be < 10M/s } ``` Or request header `x-bandwidth-limit-key: uuidA` and ```js options = { maxBandwidth: { uuidA: '1M' // match the request header }, globalMaxBandwidth: { uuidA: '10M' // match the request header } } ``` ### Motivation I code the network ingress and WAF base fastify, the bandwidth limit are important. ### Example _No response_
