Each DataSource subclass must define its own get_data method. This branch
formalizes our DataSource class to require that subclasses define an
explicit dsname for sourcing cloud-config datasource configuration.
Subclasses must also override the _get_data method or a
NotImplementedError is raised.
The branch also writes /run/cloud-init/instance-data.json. This file
contains all meta-data, user-data and vendor-data and a standardized set
of metadata keys in a json blob which other utilities with root-access
could make use of. Because some meta-data or user-data is potentially
sensitive the file is only readable by root.
Generally most metadata content types should be json serializable. If
specific keys or values are not serializable, those specific values will
be base64encoded and the key path will be listed under the top-level key
'base64-encoded-keys' in instance-data.json. If json writing fails due to
other TypeErrors or UnicodeDecodeErrors, a warning log will be emitted to
/var/log/cloud-init.log and no instance-data.json will be created.

This moves the base test case classes into into cloudinit/tests and
updates all the corresponding imports.

This has been a recurring ask and we had initially just made the change to
the cloud-init 2.0 codebase. As the current thinking is we'll just
continue to enhance the current codebase, its desirable to relicense to
match what we'd intended as part of the 2.0 plan here.
- put a brief description of license in LICENSE file
- put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0
- simplify the per-file header to reference LICENSE
- tox: ignore H102 (Apache License Header check)
Add license header to files that ship.
Reformat headers, make sure everything has vi: at end of file.
Non-shipping files do not need the copyright header,
but at the moment tests/ have it.

CloudSigma would not get any datasources loaded during cloud-init local.
Thus, when the network datasource was removed, *no* CloudSigma
datasources would be loaded.

Instead of aborting all serial using tests instead just
create a serial module in cloudinit that will create a fake
and broken serial class when pyserial is not actually installed.
This allows for using the datasource and tests that exist in
a more functional and tested manner (even when pyserial is not
found).

A few of the current tests have been continually failing
in python 2.6 based systems, due to lack of unit test
functions that are now added to ensure we can run the
unit tests (and not have to ignore those failures) on
python 2.6

On systems with a ttyS1 and nothing attached, the read attempts
that the cloud sigma datasource would do would block.
Also, Add timeouts for reading/writting from/to the serial console

This allows users of CloudSigma's VM to encode their user data with base64.
In order to do that thet have to add the ``cloudinit-user-data`` field to
the ``base64_fields``. The latter is a comma-separated field with
all the meta fields whit base64 encoded values.
