'next_uuid' Action field is replaced by 'parents'

'next_uuid' field has been replaced by 'parents' field, which is
a list of parents action linked to a current one. In that case,
I propose to remove this information (there is a column in the
dashboard) which is not readable and give unclear information
about actions workflow.

Partially Implements: blueprint planner-storage-action-plan
Depends-On: Ide2c8fc521488e486eac8f9f89d3f808ccf4b4d7
