Proposal: organization based environment variables

[shreddedbacon]

There is a use case where having environment variables able to be defined at the organization level where a common variable should be shared across all projects and environments within the organization.

The order currently is that environment level envvars override project level envvars.
This would remain the same, but organization would just be another level.

The result would be that environment level variables overrides project level, which overrides organization level.

This is a great feature, we've already seen several cases where this kind of org level env-var management would come in handy.

Big plus-one.
