Option to remove values ("Use Default Value" in adminpanel)

[DanieliMi]

Is your feature request related to a problem? Please describe.
We have imported values on store scope but in one store they are the same as the default value so we would like to remove them and just use the value of the global scope. In the adminpanel it is possible to check the checkbox "Use Default Value" which removes the value for the selected store.

Describe the solution you'd like
One possible solution could be to add a column like name_use_default_value and if 1 is passed it will remove the scoped name. The schema would be {attributeName}_use_default_value set to 1 in order to remove a value.

Describe alternatives you've considered
None so far.
