Add network schema for devices, interfaces, VLANs, VRFs, BGP configurations, MLAG, EVPN, VXLAN, routing policies, and DCI connections

- Created device schema with attributes for hostname, role, platform, and management IP.
- Added interface schema with various types, MTU, speed, and switchport modes.
- Introduced VLAN and VRF schemas with relationships to devices and interfaces.
- Implemented BGP configuration, peer groups, and neighbors with detailed attributes.
- Established MLAG domain and interface schemas for multi-chassis link aggregation.
- Developed EVPN and VXLAN schemas for overlay networking.
- Created routing policy schemas including route maps and prefix lists.
- Added DCI switch and connection schemas for inter-datacenter connectivity.
