[Feature request] pre-made global variables

[P6g9YHK6]

Is your feature request related to a problem? Please describe.
we have pre-made var for agent, client, site but nothing for global
i was working on a couple of scripts that interact with the api and for easier sharing it would be usefull to have some common global var for everyone

Describe the solution you'd like

{{global.apiurl}}
{{global.rmmurl}}
{{global.meshurl}}
{{global.baseurl}}

they would give:

rmm-api.exemple.com
rmm-rmm.exemple.com
rmm-mesh.exemple.com
exemple.com

and maybe others ?

Describe alternatives you've considered
i made these for myself but it could be usefull for everyone to have them.
