Feature Request: Add rule for sls render validation

[dawidmalina]

It would be good to render sls file to make sure we won't find issues with the syntax

the following code snippet would fail:

# the following code snippet would fail:
/path/to/file1
  file.managed:
    - contents: This is line 1

the following code snippet would pass:

# the following code snippet would fail:
/path/to/file1:
    file.managed:
    - contents: This is line 1
