0.7.1 release

[usercont-release-bot]

Hi,
you have requested a release PR from me. Here it is!
This is the changelog I created:

Changes

• remove srpm from CI test
• Fix problems catched by Review.
• Remove python2 support
• [release-conf.yaml] F30 has been branched
• update spec to 0.7.0
• podman renamed ContainerConfig to Config
• test_run_with_volumes_metadata_check: fix and optimize
• tests: prepare test env for podman as well
• make srpm fail in CI, fix it
• build srpm in CI
• mv req.in req.txt

You can change it by editing CHANGELOG.md in the root of this repository and pushing to 0.7.1-release branch before merging this PR.
I have also updated the __version__ in file:

• conu/version.py

[centos-ci]

Can one of the admins verify this patch?
