Lack of default for NovaPCIPassthrough breaks the UI JSON validation

[Julie Pichon]

The NovaPCIPassthrough doesn't seem to have a default set, and so fails the UI validation for "valid JSON strings" before the user even tries to modify it.

Steps to reproduce
------------------
1. Click on the pencil besides the Compute role to edit it
2. Services -> OS::TripleO::Services::NovaCompute

Expected result
---------------
3. Every parameter is displayed with no form validation failures

Actual result
-------------
3. NovaPCIPassthrough is shown in red with "Please enter a valid JSON string." It's not possible to save any change until this is resolved.

Additional information
-----------------------

The default is explicitly set to an empty string: https://github.com/openstack/tripleo-heat-templates/blob/master/puppet/services/nova-compute.yaml#L43-L55

    Relax JSON input validation

    Currently the JSON form input validator only passes if the value is a
    valid JSON string. This doesn't accout for cases where a paramater
    doesn't need to be set. This patch relaxes the validation rule so it
    also allows the value to be an empty string.
