- PRIS-23: Created a groovy script to assign default services for the
  first IP interface on the Guest. IP address is not required, we need
  this services just once on the VM and use it for data collection and
  power state monitoring through vCenter management IP from the node asset

- Debugging output increased also for default asset fields

- Created a method give defaultStrings if we receive null values
  for asset fields from vCenter. Instead of not creating a value
  parameter we create a value="UNKNOWN"

- Assign all IP addresses in a virtual machine and deduplicate the
  IP address from VMware Tools. There are different possibilities to
  get the Guest IP addresses depending installed VMware Tools,
  OpenVM-Tools, outadated VMware Tools or not installed VMware Tools

- Removed commented code, fixed with comment above.

- getVirualMachineIpAddresses returns now a set of InetAddresses which
  allows filtering out local loopback addresses and IPv6 link local
  address types

- The management IP is set from the configuration file to save request
  from vCenter
