Redeploy aries-endorser-service-sandbox

[esune]

In namespace bc0192-tools, using ArgoCD.

An alternative to deploying the fully fledged endorser service would be to have an aca-py deployment with auto-endorsement flags set, since the sandbox is wired-up to BCovrin Test and open to anybody.

Data migration (wallet) is required to ensure existing issuers connected to the endorser keep working.

Deployment could/should be moved to a99f4d-prod for consistency, since all of our other sandbox services are hosted there.
