new feat: exclude normal helm diff out when helm drift run RELEASE -f <valuesXXX.yaml> <local_chart_path>

[dayFlame]

My situation is that, in cluster deployed release with CHART version 1.0 and image tag 1_1, then manual edit one workload. Now going to install CHART version 1.1 and image tag 1_2.

I use helm drift run RELEASE -f <valuesXXX.yaml> <local_chart_v1.1_path> in my local, but drift found manual edit and image tag diff 1_1 -> 1_2. How to exclude image tag diff out in drift result because it's expected.

Actually, I want to merge the feature of helm drift run RELEASE from local chart and from release. The expected diff should be filtered out. If local chart value is same as manual update, it's also supposed to be filtered out.

@dayFlame, the plugin is just the wrapper around kubectl diff. So, for drift identification the comparison happens between local-chart > remote-state or helm-state > remote-state. The diff you mentioned is expected.
