Harald Seiler 5ecef9f919 Allow "deleting" url/path of repo in override
Make "null" an allowed type for the `url` and `path` properties of a
repository.  This allows "deleting" them in an override kas-file to e.g.
point a repository at a local directory instead of a git remote:

"Original" file:

    repos:
      meta-foo:
        url: https://example.org/foo.git
        refspec: badc0ffee

Override:

    repos:
      meta-foo:
        url:
        path: /path/to/local/foo

Without the explicit "nulling" of the URL, kas would start messing with
the repo in /path/to/local/foo (changing remote URL, switching to a
different rev, etc.).  With this change, we can instead force kas to use
the recipes in that directory untouched.

This tool provides an easy mechanism to setup bitbake based
projects.

The OpenEmbedded tooling support starts at step 2 with bitbake. The
downloading of sources and then configuration has to be done by
hand. Usually, this is explained in a README. Instead kas is using a
project configuration file and does the download and configuration
phase.

Key features provided by the build tool:

- clone and checkout bitbake layers
- create default bitbake settings (machine, arch, ...)
- launch minimal build environment, reducing risk of host contamination
- initiate bitbake build process

See the `kas documentation <https://kas.readthedocs.io>`_ for further details.
