Open another repo to contain all functionality of Kubernetes cluster prerequisites preflight

[allencloud]

Issue Description

Type: feature request

When sealer run a Clusterfile to start a distributed application, it would construct the cluster(including application and Kubernetes) of several nodes from the scratch.

To improve the construct efficiency, technology should previously detect all the unsatisfied conditions of the underlying infrastructure including:

• resource condition: CPU, memory, disk and so on;
• OS related condition: kernel version, os distribution version and so on;
• network condition: network interface details, firewall settings and so on;
• some others

I would like to see an independent repo which has the above goal. Since it is quite general, I think. We can not only use it in sealer ecosystem, but also some other scenarios without sealer but facing the same preflight demand.

And I found that in https://github.com/replicatedhq/troubleshoot , preflight functionality seems to be contained. Wish to see the explicit relation or comparison of this one and troubleshoot.
