Kubernetes provider not supporting pre-provisioned data

Hello there,
when using the flag --benchmark_compatibility_checking=none and a custom VM config (which I may attach if it'd be useful), it is possible to run - for example the redis_enterprise - some workloads, which will in the next stage fail with pre-provisioning error.

`Exception occurred while calling _InstallRedisEnterprise():
Traceback (most recent call last):

It would be great if that gets supported, eventually.
