Integrate graphstore dynamics in data laboratory

Remove DynamicAPI and DynamicImpl modules

Remove fake id columns from data laboratory since now they are real columns.

Use the new TimeFormat from ImportAPI and replace usage of AttributeUtils by the new setValueString method to parse values.

Change some artifact names in order to be able to install old plugins (nbms dependencies names have to match).
Update modules specification version to 0.8.2
