Description of problem:


The hosted engine storage domain is a critical part of the
managing that VM with the engine.
  
In order to reduce manual intervention, we can collect all
data and import that domain automatically.
  
The flow would be:
  
1. Analyze the VM (VM monitoring) and check if its MANAGED
2. if not MANAGED, try to import the SD
3. detect the SD details by crossmatching the domain info (we have the
   name in config) with the output of getDeviceList, to get connection
   details of ISCSI
4. import the SD
5. if SD imported, import the VM

Expected results:

After installation, when there is an ACTIVE DC where the hosted engine runs, the storage domain should be imported automatically.

After upgrade, it should be the same.
