Opsgenie 3rd party integrations aren't respecting the hardcoded priority

Issue Summary

In Opsgenie Standard plan, 3rd party integrations aren't respecting the hardcoded priority.

Since this tier plan doesn't have access to the Advanced Settings, the priority is defined manually from P1 to P5.

Alerts are being created as P3 even though the integration is set to P1 or other value.

Steps to Reproduce

1. Create/Save API (or any integration);
2. Adjust the priority to map to anything but P3;
3. Create test through Alert API.

Expected Results

The alert is created accordingly to the defined priority.

Actual Results

Alerts are not mapping to the priority set in the integration.

Workaround

No known workaround at this moment for this plan tier other than manually.
