There is a need to rebuild the module builds done in CentOS 9 Stream
internally in MBS to include them in RHEL. This is currenly a hard task,
because the RPM components included in a module are usually
taken from HEAD of the branch defined by their `ref` value.
For the rebuild task, it means we would have to ensure that the HEAD
of all RPM components points to right commit hash right before we start
rebuilding CentOS 9 Stream module in internal MBS. This is very hard
and fragile thing to do, especially if there are two different modules
using the RPM component from the same branch. This is prone to race
condition and makes the rebuilds quite complex and in some cases
not possible to do without force pushes to RPM component repositories
which is not acceptable by internal dist-git policy.
This commit fixes it by allowing overriding the commit hash while
submitting the module build. This helps in the mentioned situation,
because we can keep internal RPM components branches in 1:1 sync with
CentOS 9 Stream branches and HEAD can always point to the same commit
in both internal and CentOS 9 Stream repositories.
When the module rebuild is submitted in internal MBS,
we can use this new feature to override the `ref` for each RPM component
so it points to particular commit and the requirement for HEAD to point
to this commit is no longer there.
The `ref` is overriden only internally in MBS (but it is recorded in logs
and in XMD section), so the input modulemd file is not altered. This is
the same logic as used for other overrides (`buildrequire_overrides` or
`side_tag`).
This does not bring any security problem, because it is already possible
to use commit hash in `ref`, so the package maintainer can already change
the commit hash to any particular commit by using this `ref` value.

This will enable building modules from the new libmodulemd v3 format.
This format fixes major issue with modularity which enables clear
upgrade paths for multicontext modules.

- split logically TestViews into separate test classes
- create class scope variants of common fixtures
- use class scope fixtures where applicable (TestViews)
- remove redundant fixture 'model_tests_init_data'
- Implement new optional parameter module_stream to allow a scratch module
build's stream name to be set from the command line when also submitting a
YAML modulemd file.
- Validate that module_name and module_stream parameters can only be specified
along with a YAML modulemd file.
- Add tests to verify that module_stream sets the stream name correctly.
- Add tests to verify that module_name and module_stream are only allowed along
with a YAML modulemd file.

This also includes `from __future__ import absolute_import`
in every file so that the imports are consistent in Python 2 and 3.
The Python 2 tests fail without this.
