Add a `Open to Remote Container` option from the CLI.

[craigloewen-msft]

In the command line I want to open VS Code and have it open directly into my dev container.

Right now I do this by running code . and then clicking the "Reopen in container" button but I'd love to just open straight to the project.

Something like: devcontainer open . would address my feedback and help me out a lot.

Thanks!

Works for me exactly as you describe:

$ devcontainer open .
