HTTP input which perform a scheduled GET

[mp3monster]

It would be really good if there was an HTTP input plugin that could be given a URL which it could perform a GET operation against. This would then provide a general purpose way to retrieve information from REST endpoints for services such as CAdvisor (https://github.com/google/cadvisor).
This would mean we Fluent Bit would be able to offer a consistent manner to monitor both Podman and Docker

Initially just a hardwired URL would be a positive step. But being able to preprocess the URL so that environment variable or other variables could be used to tailor the URL would add for flexibility.
Plus being able to define one or more strings for the header - so basic auth or tokens could be injected would make the feature extremely flexible.
