Add field and checkboxes for marketplace package text blocks

Context 

We are looking to better communicate around the support offered with marketplace add-ons. This will also include further information about partner certification as the two are linked.  

For this we aim to create two automated text blocks that describe 

-> The Support provided 

-> The nature of the certification 

To make this automated we need three more elements with each package.

To Do :

1. Create two checkboxes :

• "Show certification block" 
• "Show support block" 

This will act as the 'Supported' checkbox (see attached), they will need to expose this yes/no property to the front end 

By default not ticked 

2. Create a text field called "Link to partner support" which will be a text field, as is  "Vendor" currently (see attached)

This text will need to be exposed to the front end 

Other info 

• This property is available in the marketplace edit form, not in the package.xml (so that package publisher can't self certify their add-ons)

• Only nuxeo people can edit this property
• The property should default to Not Certified  

AC :

I will see two checkboxes in the package that aren't ticked and an empty text field
