Add X-ENABLE-EFFECTIVE-FIELDS Header Support to Create Cluster API

Summary

This PR adds support for the X-ENABLE-EFFECTIVE-FIELDS header parameter to the createCluster operation in the Atlas SDK Go client. This header allows consumers (like Terraform providers) to enable/disable effective fields functionality on a per-request basis.

Changes Made

OpenAPI Specification Updates

• Added new header parameter: xEnableEffectiveFields in the components parameters section

  • Parameter name: X-ENABLE-EFFECTIVE-FIELDS
  • Type: boolean
  • Default value: false
  • Required: false
  • Description: "Flag that indicates whether to enable effective fields functionality. Set to true to enable or false to disable."

• Updated createCluster operation: Added reference to the new header parameter in the createCluster operation parameters list

Generated SDK Changes

• The OpenAPI transformation process has processed the new header parameter
• When the SDK is regenerated, it will include methods to set this header for create cluster requests

Usage Example

Once the SDK is regenerated, consumers will be able to use the header like this:

req := client.ClustersApi.CreateCluster(ctx, groupId, &cluster)
req = req.XEnableEffectiveFields(true)  // Enable effective fields
result, _, err := req.Execute()
