fix: network map namespace filter

[albertoflorez]

Summary

• When multiple NADs share the same source-portgroup annotation but exist in different namespaces, the network map NAD query now filters by namespace extracted from the network_attachment_definition override (format namespace/name). If no namespace is specified, the current behavior is preserved.
• Adds validation to reject duplicate IDs in mtv_management_network_map_overrides, preventing silent selection of only the first match.

Changes

• roles/mtv_management/tasks/_mtv_network_map.yml: Added assertion to validate unique IDs in network map overrides.
• roles/mtv_management/tasks/_mtv_network_map_process_network.yml: Added namespace filter to JMESPath query for both VMware and oVirt NAD lookups when the override contains a namespaced network_attachment_definition.

Test plan

• Verify network map creation with two NADs having the same annotation in different namespaces and overrides specifying namespace/name
• Verify network map creation still works without namespace in network_attachment_definition
• Verify duplicate ID validation fails with a clear error message

Review

Findings

_mtv_network_map_process_network.yml

1. Jinja2 filter precedence ambiguity (low risk) — '...' + __mtv_management_nad_override_ns | trim + '...' works correctly by coincidence (surrounding literals have no whitespace to strip), but intent is clearer with parens: (__mtv_management_nad_override_ns | trim). Readers will question whether trim applies to the variable or the whole concatenation.

2. Namespace extracted but NAD name not stripped — when override is my-ns/my-nad, this PR filters by namespace my-ns in the annotation query. But if downstream code matches the network_attachment_definition value my-ns/my-nad against a NAD resource named my-nad, it won't match. Worth verifying that downstream consumers also handle the namespace/name format, or the name portion gets extracted separately.

3. Near-identical blocks for VMware and oVirt — both namespace extraction lines and query constructions are copy-pasted. Not a bug, but any future fix needs applying twice.

_mtv_network_map.yml

4. Duplicate ID assertion is clean. Correct Jinja2 filter chain, good error message, proper when guard.

Verdict

Solid targeted fix. Items 1 and 3 are style nits. Item 2 is the one worth confirming — does any code downstream of this query use the raw network_attachment_definition override value for name matching? If so, it needs the namespace/ prefix stripped too.
