Parsing of image substitution incomplete

This is related to #23 in the sense that the symptom is that replacements don’t work.

The regex used to parse an image identifier in the yaml is const imageKeyword = line.match(/^ *image:/);. I had an issue where it was not working for me, because I had a config like this:

..
  containers:
    - image: test
      name: test

Which isn’t correctly parsed by the regex.

The clean solution would be to use a real yaml parser, but an ugly quick fix could be to allow for this case.

If you want to have the quick fix I can make a PR, just let me know. The correct regex is: /^ *(?:- )?image:/

Cool. Tag @shigupt202 in your PR so he can take it forward. 😃

That’s a good catch. @SamMousa would you be willing to raise a fix for the same?
