ntp: Add schema definition and passive schema validation.
cloud-config files are very flexible and permissive.
This adds a jsonsschema definition to the cc_ntp module and validation
functions in cloudinit/config/schema which will log warnings about
invalid configuration values in the ntp section.
A cmdline tools/cloudconfig-schema is added which can be used in our dev
environments to quickly attempt to exercise the ntp schema.
It is also exposed as a main in cloudinit.config.schema.
(python3 -m cloudinit.config.schema)
Fix eni rendering for bridge params that require repeated key for values.
There are a few bridge parameters which require repeating the key with each
value in the list when rendering eni. Extend the network unittests to cover
all of the known bridge parameters and check we render eni and netplan
correctly.
net: remove systemd link file writing from eni renderer
During the network v2 merge, we inadvertently re-enabled rendering systemd
.link files. This files are not required as cloud-init already has to do
interface renaming due to issues with udevd which may refuse to rename
certain interfaces (such as veth devices in a LXD container). As such,
removing the code altogether.
AliYun: Enable platform identification and enable by default.
AliYun cloud platform is now identifying themselves by setting the dmi
product id to the well known value "Alibaba Cloud ECS". The changes here
identify that properly in tools/ds-identify and in the DataSourceAliYun.
Since the 'get_data' for AliYun now identifies itself correctly, we can
enable AliYun by default.
disk_setup: udev settle before attempting partitioning or fs creation.
This attempts to use udevadm settle to wait until devices have been
fully "realized". If a device exists, there may still be events in
the udev queue that would create its partition table entries.
We need to wait until those have been processed also.
The instance-level SSH key was named 'sshKeys' and now is 'ssh-keys'.
The project-level SSH key attribute has not changed so is intentionally
not changed here.
python2.6: fix unit tests usage of assertNone and format.
python2.6 unittest.TestCase does not have the assertIsNone or
assertIsNotNone. We just have to explicitly use the unittest2
version, which we get from helpers.
The desire to use assertIsNone comes from flake8 (through hacking,
I believe).
Also, fix "{}.format('foo')" which is not valid in python2.6.
