Support remote containers

[justin-pierce]

Global settings work. I can't get workspace configuration buttons to show up while working in a container environment (they do show up if I "reopen locally").

I do have both added to devcontainer.json

    "extensions": [
        "fabiospampinato.vscode-terminals",
        "fabiospampinato.vscode-commands"
    ]

I think I have some setting somewhere to make the extension for in containers.
