Random locking failure due to CacheControl returning an empty bytes response

[j-martin]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: macOS Monterey
• Poetry version: 1.1.11

Issue

When adding new packages or locking we observed random failures where the JSON response is empty (as in b"").

Through #4717 and pypi/warehouse#10387 we (myself and @kapilt) found that CacheControl is returning empty data even though there should be serialized JSON object.

Removing session CacheControl seems to solve the issue.

fwiw, i haven't actually hit this in a while using latest poetry releases.. i think the actual issue was solved on the pypi cdn side.
