Upcoming: PyPI code freeze

[di]

PyPI will implement a code freeze from May 9th AoE - May 30th AoE, to reduce the potential for outages during PyCon & related staff PTO afterwards. No pull requests will be merged during the code freeze, unless they fall under the following exceptions:

• Security fixes
• Critical bug fixes (e.g. currently causing an outage, data loss, user-facing errors, etc.)
• Breakglass: if all four @pypi/warehouse-admins approve a PR.
