Provide a way to run the storage perf test in airgap

[bxu1999]

The current storage perf tests depends on the container image quay.io/ibm-cp4d-public/xsysbench:1.1 In airgap environments, this image might not be accessible. So need to provide a procedure how to download the image and push it to airgap clusters' private registry and then run this perf test suites.

[bxu1999]

added the following procedure for pulling and loading the image in airgap environments:

Pulling and loading the required image in airgap environment

This storage performance test suite relies on a container image: quay.io/ibm-cp4d-public/xsysbench:1.1 This image may not be directly accessible on an aigap cluster. To resolve this, follow the steps below to download the image onto an intermediary host and then copy the image to the airgap cluster, and finally load it into the cluster's private registry.

 # on an intermediary host that can access the image
 podman pull quay.io/ibm-cp4d-public/xsysbench:1.1
 podman save -o xsysbench-1.1.tar quay.io/ibm-cp4d-public/xsysbench:1.1

 # copy the above .tar file onto the airgap cluster

 # on the airgap cluster
 podman load -i xsysbench-1.1.tar
 podman tag quay.io/ibm-cp4d-public/xsysbench:1.1 <private-registry>/ibm-cp4d-public/xsysbench:1.1
 podman tag quay.io/ibm-cp4d-public/xsysbench:1.1 <private-registry>/ibm-cp4d-public/xsysbench:1.1-amd64

 podman login -u <uaername> -p <password> <private-registry> --tls-verify=false

 podman push <private-registry>/ibm-cp4d-public/xsysbench:1.1
 podman push <private-registry>/ibm-cp4d-public/xsysbench:1.1-amd64

Next make sure that in the "params.yml" file, you modify the imageurl line to below:

imageurl: <private-registry>/ibm-cp4d-public/xsysbench:1.1

Finally just follow the previous sections to run the test suites.

tested it in an airgap cluster, and the result looks good.

Below are some time duration for the run:
