I want to be able to easily store and use other cloud providers. At the moment only Azure and AWS is supported but I want to be able to use others. The ability to create others (such as DigitalOcean) would be brilliant.

I would be happy being able to store the key and secrets and have Octopus set the values in the worker as environment variables that I specify (it would also be very useful to also be able to say that this variable is an environment variable rather than needed substitution).
