[Arvindthiru]

What type of PR is this?

/kind feature

What this PR does / why we need it:

This PR adds an init container to hub-net-controller-manager, member-net-controller-manager deployment charts to install CRDs.

it also addresses some misc issues with the E2E setup,

• specifies the VM size of AKS clusters created for E2Es to be A-series, since we build our images with platform specified as linux/amd64 the corresponding VM must also match the same ARCH
• specifies platform to linux/amd64 for an hello-world app we build to test in our E2E

Which issue(s) this PR fixes:

Fixes #

Requirements:

• run make reviewable for basic local test
• Read and followed fleet-networking's Code of conduct.
• uses conventional commit messages
• includes documentation
• adds unit tests

Pull Request Overview

This PR adds a CRD installer init container to the hub and member network controller manager deployments, allowing CRDs to be installed automatically without manual kubectl apply commands. The PR also fixes E2E test infrastructure issues by specifying VM sizes and platform architecture for consistency.

• Introduces a new net-crd-installer init container that automatically installs required CRDs based on mode (hub/member)
• Updates E2E test scripts to use Standard_A2_v2 VM sizes for AKS clusters to match linux/amd64 platform requirements
• Enhances log collection to capture init container logs and adds platform specification for Docker builds
