[IMP] project: add task dependencies feature in project.task model

This commit adds two new fields in the project.task model.
The first one called 'allow_task_dependencies' is a related field to the
one project.project model. The other field called 'depend_on_ids' is a
Many2many field will contain the tasks which the current task depend on.

In the form view of project.task model, these fields are added.
