Integration with Upsun

[hedberg]

Feature description

Environment variable syncing to Upsun.com PaaS provider (created by Platform.sh).
An API for environment variables is available.

Why would it be useful?

The platform enables hosting of a wide range of applications but I haven't found a way to incorporate the Infisical CLI making secrets management hard to solve.

Additional context

By default, project and environment variables are only added to the PLATFORM_VARIABLES environment variable. To expose a variable as its own environment variable (which to me is the desirable outcome) it has to be prefixed with env:.

For example, the variable env:foo creates an environment variable called FOO.
