License environment variable is inconsistent with the rest of the Particular platform #826
Description
Describe the suggested improvement
Is your improvement related to a problem? Please describe.
The environment variable to store the license string for in-process functions (and other cloud platforms) is NSERVICEBUS_LICENSE. This differs from the main PARTICULARSOFTWARE_LICENSE variable used by Core and other desktop-based packages in the platform. This doesn't affect production deployment, but it does mean that the development experience requires two variables to be set if the developer is also working with other parts of the platform.
Describe the suggested solution
Deprecate NSERVICEBUS_LICENSE for this package in favour of PARTICULARSOFTWARE_LICENSE
