ci: cilium dualstack for load test pipeline

[camrynl]

Reason for Change:

• Creates a new stage for cilium dualstack in the load test pipeline
• Added new parameters to the load test template in order to reuse stages and detect dualstack scenarios
• Converted cilium/1.14 daemonset and operator files from .tpl to .yaml for consistency and fluid parameterization

Issue Fixed:

Requirements:

• uses conventional commit messages
• includes documentation
• adds unit tests
• relevant PR labels added

Notes:

[jpayne3506]

I checked the CNI Release Test pipeline and did not see a passing Dualstack E2E. All other changes are 🟢

lgtm, can we get a green on cni release pipeline ?

I can send the run where the dualstack stage passes, but I would also like to gather a fully green run with the latest changes once the pipeline is back up
