Using the Veeam Backup and Replication template with a read-only user results in a "403 Forbidden" from the "/api/v1/services" endpoint. The endpoint is fetched but not used by the template. Patching the template by removing the endpoint fixes the issue.

Steps to reproduce:

1. Create read-only user with "Veeam Backup Viewer" role in Veeam B&R
2. Add template to host with URL, username and password macros set
3. Wait for discovery

Result:
"403 Forbidden" from "/api/v1/services" endpoint.

Expected:
"2xx" from all endpoints.
