XenAPI: can't inject admin passwd

[Jianghua Wang]

The admin passwd is not injected into metadata for Windows VMs, meaning cloud-init cannot set the password.

stack@DevStackOSDomU:~$ nova boot --image cirros-0.3.5-x86_64-disk --nic net-id=60f82bcc-dfed-4825-8832-4a9331e2df2c --flavor 1 --admin-pass admin testVM

# the pass is not set and the specified admin passwd is not included in metadata.
$ hostname

the admin_pass exists in the config drive but doesn't exist in the metadata service:

It seems the password specified by "--admin_pass" is treated as extra metadata and only saved in config drive. But if we explicitly put the admin_pass in the metadata via "--meta admin_pass=xxxx" or add metadata from the horizon page, this passwd will be saved both in config drive or meta service:

Basing on the above test result, probably we should close this bug as just work as design.
