Consider various output options when executing a diff

[jtslear]

For some helm releases, a simple upgrade can change nearly every file as some helm charts put the version as a label or annotation for every object that gets created. This makes diff outputs a very boring read. Similar to #221 it be neat if we could ask the plugin for various options to better our format to make it easier for review.

Things to consider:

• Output that only shows what objects were changed
• Output similar to git diff where it shows just the immediate changes of an object, vs output the ENTIRE object
• Output in a programmatic format (as mention in Add support for custom output formats #221) such that we can parse and do fun scriptable things with it.

Did you consider that helm diff -C5 ... already "solves" at least your second point

😲 I had no idea this option existed. Thank you for that 🔥 tip. The rest of my proposal still stands, so I will not yet close this issue.
