Sync CircleCI Orb version
Add sync of the Prometheus CircleCI Orb version to the sync script.

preserve whitespace and enforces some indenting rules. It does preserve
comments.

Julien Pivotto c1f203a1b8 Use CircleCI parallelism
This commit uses the CircleCI parallelism features, combined with the
last changes in promu that enables this.

Now all the pull requests will be built with all the platforms again, in
less than 20 minutes.

A side effect is that we now build Prometheus for 7 more os/arch combos:
darwin-arm64 / illumos-amd64 / linux-mips / linux-mipsle /
freebsd-arm64 / netbsd-arm64 / openbsd-arm64
