The goal of this commit is to add a "Python version" of the
shape-on-image feature using a controller.
Since the whole logic to apply shapes on image is JS-based, we need
to use this URL (just like for background shapes) when we want to add
a shape by default on images in themes. When the configurator replaces a
snippet image (which the theme defines to have a shape), the shape
option should still be applied on the new image.
On the JS side, loadImageInfo() is overridden in order to mark
images (with theme default shapes) with corresponding attachment
data (original-id, original-src, mimetype).
Here is an example of the minimum xpath required to add a shape on a
snippet image in a theme:
```
<template id="s_image_text" inherit_id="website.s_image_text">
<xpath expr="//img" position="attributes">
<attribute name="src">/web_editor/image_shape/website.s_image_text_default_image/web_editor/solid/blob_1_solid_rd.svg?c2=o-color-1</attribute>
<attribute name="data-shape">web_editor/solid/blob_1_solid_rd</attribute>
<attribute name="data-original-mimetype">image/jpeg</attribute>
<attribute name="data-file-name">s_image_text.svg</attribute>
<attribute name="data-shape-colors">;o-color-1;;;</attribute>
</xpath>
</template>
```
