Run, record and document stateful migration for nginx-j2 application

[istein1]

Application source:
https://gitlab.cee.redhat.com/app-mig/mtc-apps-deployer#using-the-applications-from-the-cli-tool
(Or if needed, consider picking from the stateful workloads from
https://github.com/konveyor/mig-demo-apps/tree/master/apps)

Accomplish a migration with MTC and then also with Crane 2 of the sample app with PV data.
As Crane 2 we need to run as a namespace administrator (NOT CLUSTER_ADMIN)
(On MTC Cluster Admin is a must to perform the migration)

Deliverables:

• Record a demonstration with using MTC and with using Crane 2 to migrate the app
• Want this to be migrating from cluster-A to cluster-B
  • Use your own namespace
• Document + Share observations of issues you ran into.
  *Capture the steps for MTC to accomplish
  *Capture the steps for Crane to accomplish
  *Automate the crane steps as a bash script (team mission)
  *Note observations of both
