Feature: import aip

[jhsimpson]

A new feature request from an Artefactual client - create a new tool to allow an AIP that was stored in one Archivematica Pipeline to be imported into another Archivmeatica environment. The main use case is when a set of AIP's were produced and saved with an Archivematica instance that no longer exists.

The tool should allow a user to provide the path to a locally available AIP and the tool will:

• validate the AIP (make sure it is a valid Bag
• add an entry to the storage service database
• index the aip in the local ElasticSearch index
