Subject: meta-security: Remove unused content
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This unused content can be devided in two parts:
 - setting and feature in bitbake classes
 - tests

None are actually used by AGL.

Even if this content can be later included in distribution,
I prefer to remove it now.

Change-Id: I4e6a8ac6326986a5652a7c47614dcaa3db8cabb6
