a) It initialize organization UUID
b) Initialize tenant_id/vdc ID. (This information derived from tenant name)
Args:
uuid - is organization uuid.
name - is organization name that must be presented in vCloud director.
tenant_id - is VDC uuid it must be presented in vCloud director
tenant_name - is VDC name.
url - is hostname or ip address of vCloud director
url_admin - same as above.
user - is user that administrator for organization. Caller must make sure that
username has right privileges.
password - is password for a user.
VMware connector also requires PVDC administrative privileges and separate account.
