According to Parquet spec:
If the repeated field is a group with one field and is named either array
or uses the LIST-annotated group's name with _tuple appended
then the repeated type is the element type and elements are required.

(cherry picked from commit 346f38e)
This fixes prestodb#10383, where deployments using the legacy resource group
configuration manager were unable to run more than a single query that
used memory concurrently.
