merge from 2.6 branch: add support for EML 2.1.1 in OAI-PMH provider. https://projects.ecoinformatics.org/ecoinfo/issues/7009

Fixed a bug to use an identifier object to get a value in a vector.

Check the chain end if obsoleted by another object.
See ticket https://redmine.dataone.org/issues/7624

Use sql command to get some information rather than hazelcast.

Use a hashmap to replace a sql query to improve performance in the getHeadPID method.

In the getHeadPID method, we got the field obsoletedBy from the systemmetadata table rather than the hazelcast service.

Reformat the create and update method.

Close the input stream on the create/update method when the code aborts.
