Tutorial: Demo Environment Restore

TODO: Procedures to return the Rackspace or OpenStack environment to initial state before running any part of the ONAP demo

Extract logic from our robot test (thanks Daniel) in https://gerrit.onap.org/r/gitweb?p=testsuite.git;a=blob;f=robot/resources/test_templates/model_test_template.robot;h=add942db761d703bc8c42ca8ff61ff528f965e56;hb=refs/heads/release-1.0.0

Include instructions to run and clean the demo using authenticated REST calls from an OSS client - we need more functions than what is supported in Portal API

VF Delete/Recreate

The demo currently allows only a single VF per category (hardcoded IPs not overridden by the env file in UCA-17: Demo vFW env parameters are not overriding defaults during preloadClosed) - until then you will need to delete the current VF before recreating a 2nd one.  The procedure is as follows.

Delete the 3 artifacts in sequence

VF-Module

VNF

Service Instance

When these 3 nested artifacts are deleted then proceed back to sub-page 2 of Onboarding a VSP (and skip ./demo.sh init - only run it once to set the customer)

Full Teardown

There are 2 stacks and 5 DCAE servers outside the 2 stacks to delete
