Building RPMs

Unfortunately, RPM infrastructure is not well-developed for Python packages due to pip presence. RPM packages that are required for tarantool Python module as dependencies are not always present in target system. So we built them manually.

python3-dataclasses

Could be found in EPEL8, not presents in EPEL7.

Since all Fedora releases comes with in-built Python 3.10, we would not provide this Python 3.6 feature backport RPM for them.
