Improved error output

[jtucci]

What would you like to be added:
Improve the way the errors are logged.

• ability to suppress the diff output. sometimes I would prefer to just have a block of failed assertions ie.
  spec.name mismatch expected "name" != actual "wrong name"
• reduce what is shown in the diff output. I don't need to see a diff with all the k8s generated fields
• log all failed assertions. As of now, it only will show the first mismatch found.
• Add ability to enable colorized output
• When a resource is not found, the error message is a little bit confusing. The template it uses is gvk but if there is no name or namespace specified it formats the string with Kind:/. I think a better implementation would be to just output the top half off the resource by using a go template like

apiVersion: example.api/v1
Kind:  ExampleKind
metdata:
  name: (if it exists)
  namespace: (if it exists)
  labels: (if they exists)

Here is an example of the output that I think would make it more clear

Why is this needed:
The way errors are currently logged make it difficult to parse.
