Allow multiple Docker hosts (local and remote), ability to specify host per container.
The Docker extension only allows you to "one service at a time" (ie, localhost, or a remote).
It would be nice if when I provision a Docker container that I could choose to provision it on localhost (for speed, security) or remotely (for containers that don't need to run on the shared host and/or consume significant resources).
For example, I almost always want to provision Redis locally for speed, but if someone wanted something like MS SQL Server 2017 (4GB RAM minimum), I'd probably want to put it on a dedicated Docker remote with a high memory configuration (extreme example since I would probably install MS SQL Server on its own instance, but you understand what I mean).
