Teaser support for SVG images

[robinsonm]

I attempted to add an issue to the github repository, but due to some firewall issues, was unable to successfully do so.

That said, I'll place the same info in here and see if i could get similar results

## Bug Report

**Current Behavior**

When proxying the Teaser core component and setting the imageDelegate property to 'core/wcm/components/image/v2/image', the image tab does not have support for placing and SVG image into the component.

**Expected behavior/code**

Since the proxied component is using the V2 core image component as its delegate (which has support for SVG images) the SVG should be visible within the proxied Teaser.

**Environment**

- AEM 6.4.3

- Core Components version 2.3.2

- Java(TM) SE Runtime Environment (build 1.8.0_151-b12)

Check the error.log for messages around the XSS Filter stripping the svg.

SVG's are not rendered for security considerations.
