IDS catalog interface

[mantid-builder]

Original Reporter: Jay Rainey

This ticket is blocks : TRAC7640, TRAC9026

The methods getDownloadURL and getUploadURL in ICatalog need to be re-factored into their own interface as it's not possible to call them within a compositeCatalog (http://trac.mantidproject.org/mantid/ticket/9026). They are part of the Information Data Service (IDS), which is a separate API from ICAT. (Though, it uses investigationIds etc that are obtained via ICAT)

To resolve this issue I need to:

1. Create a new interface (CatalogInfoService) that contains the two method signatures.
2. Inherit this interface in ICat4Catalog. (I should not have to change much within this class)
3. Remove the related methods from ICat3Catalog as it does not have an IDS.
4. Remove keepAliveinminutes method from ICatalog as it's not used, and will not function as expected in the compositeCatalog. The keepAlive method is more than sufficient.

'''Note:''' the catalog algorithms that use these methods should not be affected as they call the catalog in use. Better exception handling should be put in place to ensure if a catalog is used that does not support an IDS then the user will know. The algorithms are:

• CatalogDownloadDataFiles(uses getDownloadURL)

• CatalogDownloadDataSets (uses getDownloadURL)

• CatalogPublish (uses getUploadURL)

  Keywords: ICAT,IDS
