Reduce amounts of checks when creating a template

[kdp-cloud]

Currently when creating a new template, based on an existing template, the inherited attributes are completely locked because it needs to be locked when creating a Sample Type. However, creating a new template, based on an existing one, does not mean it has to comply to the parent template but is regarded as a service to the user.

To do: The javascript that deals with locking elements should behave differently when creating a new template.

• All attributes should be removable
• Only the ISA tag should be locked (as it was in the past)
