Update README for 17.1 IR test (#533)

* Update README for 17.1 IR test

Update the 17.1 infrared test script README to show how to deploy a
virtualized workload on the deployed overcloud infrastructure. Helps
with testing by providing additional telemetry to STF required in
certain dashboards.

+A basic deployment can be deployed and connected to an existing STF deployment automatically after logging into the OpenShift cluster hosting STF from the host system.
+
+### Prequisites
+
+* Logged into the host system where you'll deploy the virtualized OpenStack infrastructure.
+* Installed infrared and cloned the infrawatch/service-telemetry-operator repository.
+* DNS resolution (or `/etc/hosts` entry) of the OpenShift cluster API endpoint.
+* Downloaded the `oc` binary, made it executable, and placed in $PATH.
+* Logged into the OpenShift hosting STF and changed to the `service-telemetry` project from the host system.
+
+### Procedure
+
+* Deploy the overcloud using the infrawatch-openstack.sh script:
+  ```bash
+  OCP_ROUTE_IP="10.0.111.41" \
+  CA_CERT_FILE_CONTENT="$(oc get secret/default-interconnect-selfsigned -o jsonpath='{.data.ca\.crt}' | base64 -d)" \
+  AMQP_HOST="$(oc get route default-interconnect-5671 -ojsonpath='{.spec.host}')" \
+  AMQP_PASS="$(oc get secret default-interconnect-users -o json | jq -r .data.guest | base64 -d)" \
+  ENABLE_STF_CONNECTORS=true \
+  ENABLE_GNOCCHI_CONNECTORS=false \
+  CONTROLLER_MEMORY="24000" \
+  COMPUTE_CPU="6" \
+  COMPUTE_MEMORY="24000" \
+  LIBVIRT_DISKPOOL="/home/libvirt/images" \
+  ./infrared-openstack.sh
+  ```
+
+## Running a test workload
+
+You can run a test workload on the deployed overcloud by logging into the undercloud and completing some additional setup to allow for virtual machine workloads to run.
+
+### Procedure
+
+* Login to the undercloud from the host system:
+  ```bash
+  ir ssh undercloud-0
+  ```
+* Complete the deployment of a private network, router, and other aspects to allow the virtual machine to be deployed:
+  ```bash
+  source overcloudrc
+  export PRIVATE_NETWORK_CIDR=192.168.100.0/24
+  openstack flavor create --ram 512 --disk 1 --vcpu 1 --public tiny
+  curl -L -O https://download.cirros-cloud.net/0.5.0/cirros-0.5.0-x86_64-disk.img
+  openstack image create cirros --container-format bare --disk-format qcow2 --public --file cirros-0.5.0-x86_64-disk.img
+  openstack keypair create --public-key ~/.ssh/id_rsa.pub default
+  openstack security group create basic
+  openstack security group rule create basic --protocol tcp --dst-port 22:22 --remote-ip 0.0.0.0/0
+  openstack security group rule create --protocol icmp basic
+  openstack security group rule create --protocol udp --dst-port 53:53 basic
+  openstack network create --internal private
+  openstack subnet create private-net \
+    --subnet-range $PRIVATE_NETWORK_CIDR \
+    --network private
+  openstack router create vrouter
+  openstack router set vrouter --external-gateway public
+  openstack router add subnet vrouter private-net
+  openstack server create --flavor tiny --image cirros --key-name default --security-group basic --network private myserver
+  until [ "$(openstack server list --name myserver --column Status --format value)" = "ACTIVE" ]; do echo "Waiting for server to be ACTIVE..."; sleep 10; done
+  openstack server add floating ip myserver $(openstack floating ip create public --format json | jq .floating_ip_address | tr -d '"')
+  openstack server list
+  ```
