Is your feature request related to a problem? Please describe. No

Describe the solution you'd like Dockerfile & docker-compose.yml files are extremely common in my work and having syntax support would be great! I would hope for the following features (in order of what I priority I personally would expect)

• Syntax checking for errors
• Code completion
• Code reformatting
• Above features depend on version of Dockerfile and docker-compose.yml file (which are contained inside the file itself)

Describe alternatives you've considered Alternative would be to not have these languages available. This would be possible, but editors commonly support them (idea suite, vscode etc. etc.)

Dockerfile & docker-compose.yml are dialects of Yaml so I would expect the solution to depend on yaml support.
