Support routed networks

Issue #, if available:
Fixes #435
Description of changes:

Generated

This pull request introduces several updates to the CloudStack provider, including enhancements to network configuration, dependency upgrades, and validation logic improvements. The changes also include a migration to the Uber mock library for mocking in tests. Below are the most important changes grouped by theme:

Network Configuration Enhancements:

• Added a NetworkMode field to the Network and CloudStackIsolatedNetworkStatus structs to support routing mode configurations. This field is also reflected in the CRDs (cloudstackclusters.yaml, cloudstackfailuredomains.yaml, cloudstackisolatednetworks.yaml). [1] [2] [3] [4] [5]
• Updated the Network() method of CloudStackIsolatedNetwork to include the NetworkMode from its status.
• Added logic to handle NetworkMode in the AddToLBIfNeeded method, ensuring that load balancer assignment is skipped for routed networks.

Validation Logic Improvements:

• Modified the ValidateUpdate method in CloudStackCluster to allow updates to the ControlPlaneEndpoint.Host field while ensuring the Port remains unchanged.

Dependency and Tooling Updates:

• Migrated from github.com/golang/mock to go.uber.org/mock for mocking in tests, updating all relevant test files and the Makefile. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
• Upgraded Go version to 1.23 and updated dependencies in go.mod files, including cloudstack-go to v2.17.0 and golangci-lint to v1.60.2. [1] [2] [3] [4] [5] [6]

These changes improve the flexibility of network configurations, enhance validation rules, and modernize the codebase with updated dependencies and tooling.

@vishesh92 it seems the checks are stuck, can you check ?

Yes. I think it's due to golangci-lint & go version.
