tempest-integrated-compute-centos-8-stream fails with version conflict in boto3

[Balazs Gibizer]

INFO: pip is looking at multiple versions of <Python from Requires-Python> to determine which version is compatible with other requirements. This could take a while.
INFO: pip is looking at multiple versions of cinder to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install cinder because these package versions have conflicting dependencies.

The conflict is caused by:
    boto3 1.19.10 depends on botocore<1.23.0 and >=1.22.10
    The user requested (constraint) botocore===1.22.10

Example run: https://zuul.opendev.org/t/openstack/build/a637bf6e68c545e59c8d091393a2307e/log/job-output.txt#7507

It seems it is blocking the nova master gate since 2021.11.09.

Marking it Critical until we figure out this is not a blocker.

11:44 < frickler> bauzas: gibi: I did "curl -XPURGE https://pypi.org/simple/botocore" and the
                  same without the "/botocore". please try another recheck

16:10 < clarkb> frickler: bauzas gibi it happens when new deps are released and then we pin
                them in constraints because pypi has a fallback for its CDN lookups that tends
                to run out of date by a couple of weeks it seems
16:10 < clarkb> openstack notices because our requirements system is really good at bumping
                and constraining new deps

After the PURGE subsequent job runs was green, so the above is solved the issue.

The only constraint I see from cinder is boto3>=1.16.51 # Apache-2.0https://opendev.org/openstack/cinder/src/branch/master/requirements.txt#L67
