Populate extended Package metadata from GOKb data

QA 2022-05-23:

Are both in the OAI-PMH XML as date times in the format YYYY-MM-DDThh:mm:ssZ

However they end up being stored as just YYYY-MM-DD, and then displayed as date time - this results in both incomplete (missing time) and incorrect (date has offset applied for tenant time zone) information being displayed in the UI

JSON example from GOKb ingest:

Issue descoped.  Properties with multiple values moved to to resolve hasMany implementation. 

Problem 1: Saving the alternate names in PackageIngest yields a typeMismatch:

 relevant code: https://github.com/folio-org/mod-agreements/compare/ERM-2059#diff-8f90bc042b7d65dfbedefaed2af641c261c5f07e246edd63d57914509c5c1e60R133-R142  -  alternatively there might be an error in the schema

Problem 2: If more than one Alternate Name is supplied from GOKb, they are always joined into one array entry:

original data:

relevant line on GOKb Adapter: https://github.com/folio-org/mod-agreements/compare/ERM-2059#diff-006982d299e392922eede4e7fa7a53ba600ae017e283c48ce189986f1b27f8deR325 

record.metadata.gokb.package.status seems already to be used for package_status?
https://github.com/folio-org/mod-agreements/blob/master/service/src/main/groovy/org/olf/kb/adapters/GOKbOAIAdapter.groovy#L321

basically working:

• Package availability scope

• Lifecycle status (see note above)

• Source data created

• Source data updated

to be done:

• the two has many fields (contentType, Alternative names)

• more extensive testing (more packages)
