include option for JIT access to VMs

Provide user with option for [JIT access](https://learn.microsoft.com/en-us/azure/defender-for-cloud/just-in-time-access-usage) though it does require [Microsoft Defender for Servers Plan 2](https://learn.microsoft.com/en-us/azure/defender-for-cloud/plan-defender-for-servers-select-plan#plan-features) to be added to the subscription so is not for everyone.
