Subject: [PATCH 1/7] Add flexibility to IMDS api-version (#793)
RH-Author: Eduardo Otubo <otubo@redhat.com>
RH-MergeRequest: 45: Add support for userdata on Azure from IMDS
RH-Commit: [1/7] 9aa42581c4ff175fb6f8f4a78d94cac9c9971062
RH-Bugzilla: 2023940
RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
RH-Acked-by: Mohamed Gamal Morsy <mmorsy@redhat.com>
Add flexibility to IMDS api-version by having both a desired IMDS
api-version and a minimum api-version. The desired api-version will
be used first, and if that fails it will fall back to the minimum
api-version.

This change allows us to retrieve the username and hostname from
IMDS instead of having to rely on the mounted OVF.

Subject: [PATCH 6/7] Azure: Retry net metadata during nic attach for
non-timeout errs (#878)
RH-Author: Eduardo Otubo <otubo@redhat.com>
RH-MergeRequest: 45: Add support for userdata on Azure from IMDS
RH-Commit: [6/7] 4e6e44f017d5ffcb72ac8959a94f80c71fef9560
RH-Bugzilla: 2023940
RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>

When network interfaces are hot-attached to the VM, attempting to get
network metadata might return 410 (or 500, 503 etc) because the info
is not yet available. In those cases, we retry getting the metadata
before giving up. The only case where we can move on to wait for more
nic attach events is if the call times out despite retries, which
means the interface is not likely a primary interface, and we should
try for more nic attach events.

Subject: [PATCH 4/7] Azure: eject the provisioning iso before reporting ready
(#861)
RH-Author: Eduardo Otubo <otubo@redhat.com>
RH-MergeRequest: 45: Add support for userdata on Azure from IMDS
RH-Commit: [4/7] ba830546a62ac5bea33b91d133d364a897b9f6c0

Due to hyper-v implementations, iso ejection is more efficient if performed
from within the guest. The code will attempt to perform a best-effort ejection.
Failure during ejection will not prevent reporting ready from happening. If iso
ejection is successful, later iso ejection from the platform will be a no-op.
In the event the iso ejection from the guest fails, iso ejection will still happen at
the platform level.

Subject: [PATCH 2/7] Azure helper: Ensure Azure http handler sleeps between
retries (#842)
RH-Author: Eduardo Otubo <otubo@redhat.com>
RH-MergeRequest: 45: Add support for userdata on Azure from IMDS
RH-Commit: [2/7] e8f8bb658b629a8444bd2ba19f109952acf33311
RH-Bugzilla: 2023940
RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
RH-Acked-by: Mohamed Gamal Morsy <mmorsy@redhat.com>
Ensure that the Azure helper's http handler sleeps a fixed duration
between retry failure attempts. The http handler will sleep a fixed
duration between failed attempts regardless of whether the attempt
failed due to (1) request timing out or (2) instant failure (no
timeout).
Due to certain platform issues, the http request to the Azure endpoint
may instantly fail without reaching the http timeout duration. Without
sleeping a fixed duration in between retry attempts, the http handler
will loop through the max retry attempts quickly. This causes the
communication between cloud-init and the Azure platform to be less
resilient due to the short total duration if there is no sleep in
between retries.

- Detect a Python version change and clear the cache (#857)
summary: Clear cache when a Python version change is detected
When a distribution gets updated it is possible that the Python version
changes. Python makes no guarantee that pickle is consistent across
versions as such we need to purge the cache and start over.

Fix MIME policy failure on python version upgrade (#934)
Python 3.6 added a new `policy` attribute to `MIMEMultipart`.
MIMEMultipart may be part of the cached object pickle of a datasource.
Upgrading from an old version of python to 3.6+ will cause the
datasource to be invalid after pickle load.
This commit uses the upgrade framework to attempt to access the mime
message and fail early (thus discarding the cache) if we cannot.
Commit 78e89b03 should fix this issue more generally.
