Delete redplanet

[emma-imber]

What does this change?

Deletes all files related to the running of redplanet - this includes launchpad, which is used by the redplanet code.

There will also be PRs needed to delete the switch in frontend, and references to the switch in dotcom-rendering. We can also look to remove redplanet from the vendor list when these code changes have been made.

Why?

We have permission to remove redplanet from the site.

Yeah there seems to be roughly 200-400ms variability between runs. I guess this PR is still a little quicker than the changeset one! Would be good to have a think about how we could make the testing a little more reliable
