Upgrade environment pipeline

We need to be able to update earlier deployed environment without data lost.

Pipeline must support environment upgrade with next parameters: 

• Target cluster
  • Predefined clusters
  • New
• Environment name
  • Predefined set 
  • Custom name
• Resource, number of replicas, labels for affinity rules - helm configuration (how to work with that in rancher)
• UI modules versions
  • from platform-complete(specific branch stripes.json) 
  • UI selection (how to collect all available modules) (some of them could be skipped)
• Services versions
  • from database
  • from platform-complete(specific branch) 
  • UI selection (how to collect all available modules)
