Support emulation configuration on HyperConverged CRD

Is your feature request related to a problem? Please describe:
Previously end users were able to easily enable software emulation by modifying the kubevirt-config
ConfigMap. This is now deprecated, and emulation is configured on the KubeVirt object. The KubeVirt object is not modifiable in a HyperConverged-managed environment.
Describe the solution you'd like:
Support the developerConfiguration
options on the HyperConverged CRD, and pass them to the KubeVirt object. (Or just support an option specifically for enabling emulation.)
Describe alternatives you've considered:
I see KVM_EMULATION
env can be set on the Subscription, but this is not straightforward for an OpenShift administrator using OperatorHub in the OpenShift Console.
Additional context:
I am a Red Hat partner and was hoping to evaluate compatibility of our security product with OpenShift Virt workloads using emulation first, before going through the expense of provisioning metal compute nodes. This is purely for dev work.
This is by design: the performance impact of KVM_EMULATION
is too heavy to make it it useable even on POCs so it's not exposed as a top level configuration option.
Please consider about enabling nested virtualization on the bare metal nodes instead.
