With this patch support for building multiple targets in parallel with
bitbake is now supported.
Changes:
- Its now possible to state a list of targets under the target key in
the configuration file.
Example:
target:
- product-image
- product-update-image
- Its now possible to define multiple targets in the kas command line.
Example:
$ kas build --target product-image --target product-update-image \
kas.yml
- Its now possible to define multiple targets via the environment:
Example:
$ export KAS_TARGET="product-image product-update-image"
$ kas build kas.yml

Captain Hindsight: We should have never committed 13a87cb8c7 ("Allow
to define task in config and environment") without forwarding the file
version. Without this, no config file writer can tell kas versions
apart that support task control from those that don't.

Use a separately incremented integer to track the configuration file
format version. We start with 2 due to the change that 23c3a951f6
introduced. 1 is declared to be equivalent to the original '0.10'.
The separate versioning has the advantage of being able to increment it
already during the development cycle, and using it with config files
that test/exploit the new format.
Using an integer has the advantages of a) differentiating it clearly
from the now independent kas version and b) simplifying the version
parsing. We can now also remove the string type restriction.

If the configuration file structure changes over time, it might
introduce incompatibilities.
This patch introduces versioning of configuration file.
Configuration files needs to add a 'version' entry into their 'header'
like this:
header:
version: '0.9'
After loading this file, the version is checked agains kas version.
Every version 'M.m.p' of kas is allowed to load configuration files with
version 'M.m' and all versions backwards up to and including
the '__compatible_version__' from kas/__version__.py
