Associated with LFRic ticket. #3624

@christophermaynard, we already have an issue for global reductions, it's #489. There are other built-ins there besides min and max, and that is mean and rms.

We can keep this issue and make #489 as the overarching issue for all of them, or we can close this issue as a duplicate of #489 and implement #489 in 2 PRs: 1) min and max, 2) mean and rms. I am not sure about the support for mean in the LFRic infrastructure and we need it for rms.
