* Mutation is responsible for setting value to a {@link GlobalAttributeSchemaContract#isUniqueGlobally()}
* in {@link EntitySchemaContract}.
* Mutation can be used for altering also the existing {@link GlobalAttributeSchemaContract} alone.
* Mutation implements {@link CombinableLocalEntitySchemaMutation} allowing to resolve conflicts with the same mutation
* if the mutation is placed twice in the mutation pipeline.
