Create e2e tests

There a few scenarios here:

• You can create wwn's on creation.
• Delete in the edit mode by manual deleting each item or by unchecking the corresponding check box
• You should not be able to create a wwn with a wwn name that exists, but you can create a wwn with the same name when you have deleted it before even without submitting.
• The information to each hosts differs on the information it holds.
