📝 [Proposal]: Add support to create client from existing client #3107
Description
Feature Proposal Description
I believe there should be a way to pass custom fasthttp client in to the fiber http client, to allow more granular fine tuning by the users.
Alignment with Express API
HTTP RFC Standards Compliance
API Stability
Feature Examples
Naming can be improved but something along the lines:
cc := client.NewWithFasthttpClien(&fasthttp.Client{...})
