"""

Standalone application that leverage openmano vmware connector work with vCloud director rest api.

 - Provides capability to create and delete VDC for specific organization.
 - Create, delete and manage network for specific VDC
 - List deployed VM's , VAPPs, VDSs, Organization
 - View detail information about VM / Vapp , Organization etc
 - Operate with images upload / boot / power on etc

 Usage example.

 List organization created in vCloud director
  vmwarecli.py -u admin -p qwerty123 -c 172.16.254.206 -U Administrator -P qwerty123 -o test -v TEF list org

 List VDC for particular organization
  vmwarecli.py -u admin -p qwerty123 -c 172.16.254.206 -U Administrator -P qwerty123 -o test -v TEF list vdc

 Upload image
  python vmwarerecli.py image upload /Users/spyroot/Developer/Openmano/Ro/vnfs/cirros/cirros.ovf

 Boot Image
    python vmwarerecli.py -u admin -p qwerty123 -c 172.16.254.206 -o test -v TEF image boot cirros cirros

 View vApp
    python vmwarerecli.py -u admin -p qwerty123 -c 172.16.254.206 -o test -v TEF view vapp 90bd2b4e-f782-46cf-b5e2-c3817dcf6633 -u

 List VMS
    python vmwarerecli.py -u admin -p qwerty123 -c 172.16.254.206 -o test -v TEF list vms

 List VDC in OSM format
  python vmwarerecli.py -u admin -p qwerty123 -c 172.16.254.206 -o test -v TEF list vdc -o
