Use _links section to drive available actions on ConfigTableRow

[ehuelsmann]

Currently, the availability of actions in the rows of the config table configuration items are determined client side based on the roles assigned to the user.

However, according to our framework design, the actions available to the user, must be driven by the API responses. This means that

• The services should be responding with _links sections on the individual items in the returned collections
• The client side should tie the availability of the actions to data received in the _links section.
