Prometheus: Upgrades http client to 1.30

[bergquist]

Creating a new PR was easier then resolving all merge conflicts in #47707

Contains the fix in prometheus/client_golang#1022

PR LGTM, but there were a lot of changes between 12.1 and 13.0 of the Prometheus client library so I recommend careful testing.

The backport to v9.1.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-53901-to-v9.1.x origin/v9.1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x a74681036e1d455fee0543d1ae1481cee32f655d
# Push it to GitHub
git push --set-upstream origin backport-53901-to-v9.1.x
git switch main
# Remove the local backport branch
git branch -D backport-53901-to-v9.1.x

Then, create a pull request where the base branch is v9.1.x and the compare/head branch is backport-53901-to-v9.1.x.

Good point. lets run it internally for a while until we backport it to 9.1.x

FYI prometheus/client_golang#1117

prometheus/client_golang#1117 is fixed now, so we should wait for v1.13.1 (or whatever's next) before backporting
