Add formatting option for ignoring multiline statements

[rcjsuen]

RUN apt-get update -y && \
    apt-get install -y curl && \
            git \
            make

For some instructions where the RUN has multiple "layers" like the above, users may not want it to be reformatted back to the following.

RUN apt-get update -y && \
    apt-get install -y curl && \
    git \
    make

Hi @rcjsuen, thanks a lot for working on this project! Are there any plans on fixing this issue?

I don't know if it'd be easier to implement, but to me it looks even better if ampersands && are moved to the next line:

RUN apt-get update -y \
    && apt-get install -y \
        git \
        make

So, essentially you just need to indent the lines not starting with && by one level.

@tagirb The desire is there but I haven't really acted on it due to microsoft/language-server-protocol#567 which makes the experience of toggling this cumbersome for some LSP clients. I suppose I could always implement it and then improve on it later so that there's at least a temporary stopgap.

This suggestion would probably work better as a separate enhancement request. Most shells work with && but I believe PowerShell does not use that syntax.

I know this has taken a long time to get addressed but clients can now ignore multiline instructions when calling the API. I've opened #88 to add a flag to the CLI to support this.

@diegocars Thanks for reaching out and bringing this to my attention. This isn't possible in the extension at the moment but it can be with a fix. I'll take a look.

@diegocars I've opened microsoft/vscode-docker#2976 to enable support for this option in the VS Code extension.
