feat: add Grafana tutorial and templates

[rjan90]

Porting over the Grafana dashboard tutorial from here: filecoin-project/lotus#11276 and updated in: filecoin-project/lotus#12934.

Can be merged once 12934 lands

@rjan90 : would it be helpful for me to review so this can land?

[rjan90]

I think the progress on this PR stopped, when I mentally expanded the scope of this work by trying to write up "how to setup Graphing on a remote machine", but for now I think setting it up locally is just fine. I will look at doing a cleanup of this PR on 2024-09-30

I trust your judgement here, but I would look at how to reduce the duplication between this and filecoin-project/lotus#12934 . Ideally we're doing more pointing from one to the other than copy/pasting

I have reduced the duplication by pointing to the https://github.com/filecoin-project/lotus/blob/master/metrics/README.md for instructions.
