Description of problem:
The VM status is always "Running(Provisioning)" and after a long time becomes "Running(Provisioning Timeout)" if set"Provisioning.Enabled=n".
And there's no "/var/lib/waagent/provisioned" file generated.

Version-Release number of selected component (if applicable):
WALinuxAgent-2.1.5/2.1.6

RHEL Version: RHEL-7.3-20160901.1

How reproducible:
100%

Steps:
1. Prepare a VM on ASM mode. Set "Provisioning.Enabled=n" into the /etc/waagent.conf
2. Run "waagent -deprovision -force"
3. Deallocate this VM. Capture an image with "I've run waagent -deprovision" checked.
4. Create a VM base on this image.
5. Check the VM status. Check if the /var/lib/waagent/provisioned file is generated.

Actual result:
The VM status is Running(Provisioning) and after a long time becomes "Running(Provisioning Timeout)"
There's no /var/lib/waagent/provisioned file inside this VM.

Expect result: 
The VM status is Running.
There's /var/lib/waagent/provisioned file located. 

Additional Info: 
It works well in WALA-2.0.16.
