Feature Request: Support for external OpenSearch clusters (Authentication, Multi-node, and TLS options)

[osmontero]

Describe the feature

Currently, the integration with OpenSearch is primarily focused on local or default deployments. I am proposing an enhancement to the utmstack.yml configuration to allow UTMStack to connect to external OpenSearch clusters. This would include support for multiple nodes, credential-based authentication, and flexible TLS certificate handling.

Use Case

In enterprise environments or cloud-native deployments, users often need to:

• Offload Data: Use managed services like AWS OpenSearch, Aiven, or dedicated internal clusters.
• High Availability: Connect to multiple nodes in a single cluster for failover and load balancing.
• Security Compliance: Use specific service accounts (RBAC) and handle custom or self-signed certificates without failing connection checks.

Proposed Solution

I suggest extending the utmstack.yml to include the following parameters:

opensearch:
  servers: ["", "", ...]
  user: ""
  password: ""
  skipCertValidation: true/false
