Templating query arguments for http_scrape

[mans2singh]

A note for the community

My use case is that I need to pass start and end time parameters to the http request as query parameters.

I have checked the documentation for http_scrape but did not this option.

Use Cases

The http_scrape source allows periodically scraping an endpoint using scrape_interval_secs. It would be great if we can allow templating query parameters with functions which can be used by endpoint to customize the response. One example can be start_time query parameter, which could be templated as {{ now() }}.

Attempted Solutions

I was not able find any way in http_scrape to pass such arguments so am requesting a feature enhancement.

Proposal

Allow templating query parameters to be templates which can invoke vrl functions.

Maybe we should first solve #14758 and the this issue - so that During this issue also the body could also be templated
