[db/v1/instances] missed availability_zone field - trove database dbaas

[zhekazuev]

Description

I have identified a missing field in DB V1 - availability_zone.

This field is crucial for terraform-provider-openstack/openstack_db_instance_v1 for some OpenStack installations: terraform-provider-openstack/terraform-provider-openstack#1644.

Expected Behavior

The availability_zone field should be present in DB V1 to ensure.

Proposed Solution

I propose to add the availability_zone field to DB V1.
