Add device tag support to Prometheus metrics

Browse Source 
- Add 'tag' label to all device metric descriptors
- Update exportWithTags helper to create separate metric series per tag
- Update all device export functions (UAP, USW, UDM, USG, UXG, PDU, UBB, UCI) to include tags
- Update all label arrays (VAP, Radio, Port, etc.) to include tag label
- Devices with multiple tags create multiple metric series (one per tag)
- Devices without tags export with tag=""

Requires unpoller/unifi#92
