Get publication and award metadata from Sympletic Elements

[cc-a]

When creating/editing datasets, users must be able to associate publications and awards that are catalogued by the College in Symplectic Elements (SE).

The data repository needs to be able to get hold of/store the relevant publication/award metadata so it can be presented to the via a friendly UI for when creating deposits (see related issue).

I see two possibilities:

1. Relevant metadata is pulled from SE as and when required. This is probably the simplest approach but depends on SE providing a suitable interface for retrieving the metadata. It also requires SE to be available whenever a deposit is created.
2. We maintain a database table/index in the data repository with the desired metadata that is synced with SE. This is a more involved but decouples the systems more. This would also work if SE can only push data.
