More complex upgrade testing

[butonic]

I don't know what we are currently testing regarding upgrades, but it would be great to cover upgrades between OC server versions with additional conditions:

• complex setup:
  • 2 ldap servers
  • SAML auth
  • Guest accounts without SAML
  • galera cluster
  • load balancer and two apache servers
  • redis
  • objectstorage
  • antivirus
  • file firewall
  • well ... all the enterprise apps ...
• filled with data
  • 100K users
  • 100K groups
  • 10M files
  • 100K shares to users, 10k shares to groups, 10k external shares
• include large file (100GB) upload test
• run testsuite with IE11 & EDGE

related #329 so we have a testsuite we can give our customers

load balancer and two apache servers

This shouldn't make a difference for upgrade scenario

filled with data

That's the hardest part -> we would need to come up with a scripting to pre-fill the data. Make a snapshot then

I am missing:

• what you want to verify at the end?
• how you want to verify it?
