feat(gatsby-core-utils): Add support httpAgent

[dhoko]

👋

Description

We use gatsby-source-prismic inside our setup, and it's linked to these dependencies.

But the plugins don't support the Agent out of the box. As we use a proxy inside our CI we need to have this option else we get this error RequestError: connect ENETUNREACH xxx

Hey! Thanks so much for opening this pull request!

Sadly this PR got stale and didn't have any activity for some time. We're trying to do better with PR reviews! To get a better overview of all actionable PRs we're going through all open PRs and triage them. Since we won't be able to do everything and adding new features always means added maintenance burden, we have to be more picky about what's beneficial for the average user and the project itself longterm.

Having said all this, we dropped the ball on this PR and we're sorry about not responding to it earlier. As said above, we want to do better in the future but here we should have communicated earlier what will happen with the PR.

In the meantime Gatsby 5 and related packages were released. You can check our Framework Version Support Page to see which versions currently receive active support. Please try the mentioned issue on the latest version (using the next tag) and if you still see this problem, open a new bug report. It must include a minimal reproduction.

We absolutely want to have you as a contributor and are sorry for any inconveniences we caused with replying too late to this PR.

Thanks for submitting to Gatsby! 💜
