How Has This Been Tested?

Created a shared network with gateway/netmask/startip/endip, Checked the network cidr/gateway after the following operations - added more guest ip ranges to the shared network, removed some ranges and added new ranges, removed all ranges and added new ranges. Deployed instances on the shared network.

How did you try to break this feature and the system with this change?

Pull Request Overview

This PR enhances shared network functionality by allowing network CIDR and gateway fields to store comma-separated values representing multiple IP ranges. When guest IP ranges are added or removed from a shared network, the corresponding CIDR and gateway values are automatically updated to reflect all active ranges.

Adds utility methods for managing comma-separated strings and extracting first values
Modifies network CIDR/gateway management to support multiple values during IP range operations
Updates API responses to display only the first CIDR/gateway value for backward compatibility
