Feature Request: Global environment variables

[bverkron]

Is your feature request related to a problem? Please describe.
When I need to use the same environment variable in several stacks it's annoying to have to re-define and populate that variable in each stack individually. It's additionally frustrating when that variable needs to be changed and I have to go into each separate stack to change it. I'm human and I can miss some or make mistakes. :)

Describe the solution you'd like
It would be helpful to have a global area to define / load environment variables into and then maybe a toggle or other mechanism to specify whether a stack should load those global environment variables.

Describe alternatives you've considered
Not sure :/

Additional context
One example of common variables I need in several stacks is credentials for a remote mail server for sending notifications. Another is backup configuration values for a docker-volume-backup sidecar container I have in almost all my stacks (10+). Much of that configuration is the same across all instances of that sidecar container and I have to go into each of the 10+ stacks and configure the same thing and then do it all again if I have to add a new env value or modify one. Quite painstaking.

#7474 might be related development wise. Global variables, if implemented, should work in conjunction with "local" variables at the stack level and one should not override the other.
