openshift profile: tuning for NVMe devices

Browse source 
AWS Nitro instances need special tuning for NVMe devices:
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/nvme-ebs-volumes.html#timeout-nvme-ebs-volumes

[sysfs]
/sys/module/nvme_core/parameters/io_timeout=4294967295
/sys/module/nvme_core/parameters/max_retries=10

This tuning should probably be moved to Cloud Provider-specific profiles
once the functionality is implemented.
