Add WMCS domains to HSTS preload list
Open, LowPublic

Description

We should add the WMCS domains, toolforge.org, wmcloud.org and wmflabs.org to the HSTS preload list: https://hstspreload.org/

To be eligible, we need to add the includeSubDomains and preload directives to the HSTS header.

All 3 domains are on the publicsuffix list, so the web form doesn't work and someone will need to manually contact them, see https://hstspreload.org/#tld

Are there any subdomains we anticipate we might not want or be able to support HTTPS on?

We have at least checker.tools.wmflabs.org that does not currently support HTTPS, although I imagine it should be trivial to add if necessary. wmflabs.org and wmcloud.org likely contain other similar cases not managed by us, but adding HSTS for at least Toolforge.org does make sense.
