storage validation utility

Utility to run some basic storage validation tests against a harvester installation.

The utility uses a configuration file to driver the input for the validation.

At minimal a config.yml with following information is needed

namespace: default 
imageURL: "https://download.opensuse.org/repositories/Cloud:/Images:/Leap_15.6/images/openSUSE-Leap-15.6.x86_64-NoCloud.qcow2"
storageClass: lvm
snapshotClass: lvm-snapshot
vmConfig:
  cpu: 2
  memory: 2Gi
  diskSize: 10Gi
skipCleanup: false
timeout: 600

Field details are as follows:

Field	Description	Required	Default
namespace	namespace to run tests in	no	"default"
imageURL	url to a cloud image	yes
storageClass	storage class to be used for running tests	no	defauts to cluster default storage class
snapshotClass	snapshot class associated with storage class to be used for snapshot operations	no	defaults to a snapshot class from identified storage class
vmConfig.cpu	cores in provisioned VM	no	2
vmConfig.memory	memory of provisioned VM	no	2Gi
vmConfig.diskSize	size of vm boot disk	no	10Gi
skipClean	skip clean up of resources after validation run, useful for debugging failures	no	false
timeout	time in seconds to wait before timing out the validation run	no	600 seconds

To run

storage-validator accepts following flags

storage-validator -h
Usage of /tmp/storage-validator:
  -config string
    	Path to config file (default "config.yaml")
  -debug
    	Debug mode
  -kubeconfig string
    	Paths to a kubeconfig. Only required if out-of-cluster.

Sample output of utility will be as follows

storage-validator -config ./sample/config.yaml
