Few tweaks like adding EndPointUri to both the import and export jobs
Updated ExportDatabaseJob to use Cloud configuration settings when
parameters are not provided

It always picks the latest database in Sql.Legacy with a backup prefix
and exports it to Storage.Backup as <sourcedatabasename>.bacpac if it
does not exist already

Update ImportDatabaseJob to use Cloud configuration settings when

It always picks the latest backup*.bacpac from Storage.Primary and imports
it into the same named DB in Sql.Primary if it does not exist already
