Some e-resource packages are only available to a set of organisations/consortia/regions. Following
ERM-2306 a list of these constraints can be stored for each package. This story is to add populate this information when harvesting data from GOKb.
There are two ways in which the relevant information is available from the GOKb package harvest in depending on the content of the //package/global tag which is already used to populate the availabilityScope
IF the <global> / availabilityScope == "Local" then use the content of //package/curatoryGroups/group/name to add values to the availabilityConstraints
IF the <global> / availabilityScope == "Regional" OR "Consortium" then use the content of //package/globalNote
On updating an existing package the behaviour should be to remove all existing constraints and replace with ones in new package metadata
