Describe the bug
Deploy OVF in content library using library.deploy, but the config in ova spec file does not work as expected. The following fields are not working:

1. power on
2. waitForIp
3. Property mapping

To Reproduce
Steps to reproduce the behavior:

1. Import this (from VMware network) to content library: http://build-squid.eng.vmware.com/build/mts/release/bora-18567835/publish/edge-gw-2.1.0.0-18567835_OVF10.ovf
2. Generate ova spec, and set VM name, set powerOn=true, waitForIp=true, and set connectionString in PropertyMapping
3. Deploy using "govc library.deploy path_to_the_vm_in_lib my_vm_name -options path_to_my_ova_spec.json"

Expected behavior
Expect the VM to be deployed with powered on, with the OVA property "connectionString" to be set.

Affected version
0.26.1, Mac

Screenshots/Debug Output
Actually, the VM is deployed, and NOT powered on automatically, and the property is NOT set as expected.
