Workaround requests issue (#191)

See
#188
for context on the bug itself. The problem is that contract tests have
transitive dependency on `requests~=2.7`, which pulls in 2.32.0, which
has an issue with current version of docker. To fix this, we temporarily
take a hard dependency on 2.31.0, which does not have the issue. This
code can be removed once we upgrade successfully to 2.32.0.
