1. Changed ModuleBuild's context property to db column, it's
non-nullable and default value is '00000000' to keep it consistent
with previous behaviour.
2. Changed ModuleBuild.contexts_from_mmd to return a tuple of
(ref_build_context, build_context, runtime_context, context).
3. Updated tests affected by this change.
- Change the type of build from modulemd to just module
- Change build output type from modulemd to file
- Provide the typeinfo also for the modulemd.yaml output
- Convert dashes to underscores for build version (i.e. mbs stream).
koji build versions can't have dashes - we can provide real value in
the extra section
- Add name, stream, version data into build extra section
- Add tool information for modulemd
- Add buildroot components from host running mbs
- Added few methods licensed under BSD 3-clause (from atomic-reactor)
This commit prepares a directory with outputs that will be uploaded to
koji (just the mmd file for now). It also adjusts koji_import to call
CGImport with the metadata and the directory to import the results.
Last step will be to call this method at the end of successful module
build
