[SRU][FFE] update walinuxagent to 2.0.12

[Ben Howard]

[SRU JUSTIIFCATION]
Microsoft has released a new version of the WALinuxAgent 2.0.12. This release has a number of important fixes for running Ubuntu on Windows Azure.

[ISSUES FIXED]
Support page blob for status blob: on some instance types, provisioning status may not be reported back when using extensions.

Fix extension status on disable success: when extension is issued disable command, the state is set to "installed," causing extensions to fail.

Update shared config handler: on some instance types, provisioning may fail due to the interface not having DHCP.

[TEST CASE]

Test Case 1:
- Launch Ubuntu instance
- Upgrade walinuxagent from -proposed
- Check /var/log/waagent for errors
- Reboot
- Check /var/log/waagent.log for errors
- Confirm that /var/log/waagent.log is running

Test Case 2:
- Shutdown instance from Test Case 1
- Capture VM
- Launch new instance from Capture VM
- Confirm instance comes up with new identity
- Confirm /var/lib/waagent/SharedConfig.xml exists
- Confirm that "waagent" is running

Test Case 3:
- Build new image from -proposed
- Boot new image
- Confirm that instance provisioned

[REGRESSION POTENTIAL] WALinuxAgent 2.0.12 is mostly bug fixes. However, the contains a number of new features for supporting other distros. The default Ubuntu configuration and integration w/ Cloud-init mitigates these risks.

[ORIGINAL REPORT]

Microsoft has released a new version of the WALinuxAgent 2.0.12. This release has a number of important fixes:

Support page blob for status blob
https://github.com/Azure/WALinuxAgent/commit/8e506f9696e174fa79b5384af23fed35848d636e

Fix extension status on disable success
https://github.com/Azure/WALinuxAgent/commit/b655adb4b26ef1723c409fa60ac6696de875853e

Update shared config handler
https://github.com/Azure/WALinuxAgent/commit/9d3b061ae102967b4bbeab52089dc867b7a51fae

The first two are related to the VM extension feature, which is widely used on Azure either directly by customers or via marketplace templates (i.e. Docker+Ubuntu).

The first patch fixes an issue on the Premium Storage stack that would cause VM extensions and templates to break and provisioning to fail. This fix is the main crux for requesting the FFE.

Seems like mostly (if not exclusively) bugfixes. FFe granted
