Create Release Notes - 2.4

We need to collect the content that will be included in 2.4GA Release Notes, considering the following sections, if applicable:

• New features
• Resolved issues
• Technology preview features
• Link to supported configurations
• Known issues
• Deprecation notices [1]
• Removed features
• Replaced features

Deadline for contributions: November 30th, 2018
This deadline is intended to have a basic collection of notes to begin the draft.

[1] From this release and to align with doc practices of other RH products, we'll distinguish deprecation as an announcement to discourage use of a feature, from removal which is the actual feature withdrawal from the product and documentation.
