Database locked errors during iosxe_interface_ethernet parallel creation with source_templates

[coffmant]

IOS-XE 17.9.5

We are using a for_each loop to create iosxe_interface_ethernet interfaces en masse. Each port is using an iosxe_template to supply the interface parameters.

The first creation succeeds. Other creates that are running in parallel fail with this lock error.
