Omit "empty" values from displayed data for created & deleted objects

[jeremystretch]

Plugin Version

v0.4.0

Proposed functionality

When displaying the serialized representation of objects that have been created or deleted within a branch, omit any empty values (null, empty strings, empty arrays, etc.) from the output. For example, creating a site named "New Site" will show the following data in the "after" state of the change:

asns: []
comments: 
custom_fields: {}
description: 
facility: 
group: None
latitude: None
longitude: None
name: New Site
physical_address: 
region: None
shipping_address: 
slug: new-site
status: active
tags: []
tenant: None
time_zone: None

Omitting empty values leaves only fields which contain meaningful data, namely the name and slug fields:

name: New Site
slug: new-site

This more closely resembles the behavior when modifying an existing object, where only the modified fields are shown.

Use case

This would reduce noise in the change log and simplify human review.
