Description

Add support for EVPN instance profile configuration on VLANs, enabling both manual EVI and auto EVI with profile modes.

Changes

• Add evpn_instance_protected mapping for manual EVI configuration
• Add evpn_instance_profile mapping for auto EVI with profile support
• Add evpn_instance_profile_protected mapping for auto EVI protected mode
• Keep existing evpn_instance and evpn_instance_vni mappings (now use new provider YANG path)

Dependencies

Depends on Provider PR: CiscoDevNet/terraform-provider-iosxe#349

This PR requires the provider changes to be merged first, as it references new provider attributes.

Testing

• ✅ Pre-commit hooks passed (terraform fmt, tflint, terraform-docs)
• ✅ Local testing validated with manual EVI mode on Cat9k
• ✅ Local testing validated with profile mode on Cat9k (after manual L2 profile creation)
• ✅ Terraform plan/apply/destroy successful

YAML Configuration Example

Manual EVI Mode:

vlan:
  vlans:
    - id: 100
      evpn_instance: 100
      evpn_instance_vni: 10100
      evpn_instance_protected: true

Profile Mode (NEW FEATURE):

vlan:
  vlans:
    - id: 100
      evpn_instance_profile: MY_EVPN_PROFILE
      evpn_instance_profile_protected: true

Breaking Change Migration

The module maintains backward compatibility - users continue using the same YAML field names (evpn_instance, evpn_instance_vni), which now map to the new provider attributes that use the current YANG path.
