When operating on a remote VS Code Server, Remote Containers still executes on my local machine

[dmarszk]

Issue Type: Bug

Scenario:

• VS Code Workspace is on a remote server (accessed through VS Code Server via SSH)
• The remote server is running Docker host
• I attempt to attach to the running container via Remote Containers
• Remote containers executes on my local machine instead of the remote server (effectively not being able to access the remote host)

Extension version: 0.148.1
VS Code version: Code 1.51.1 (e5a624b788d92b8d34d1392e4c4d9789406efe8f, 2020-11-10T23:34:32.027Z)

One other issue connected to this: when connected to a SSH remote, or when docker.host is non-local, clicking on "Open Folder in Container" should show a file picker on the remote host and not on the local machine.

Addressing the 'attach' case in #4072. The more general support for Remote-SSH is tracked with #2994.
