Pin setuptools==57.5.0 to workaround install problem. (ibm-functions#153)

falkzoll · web-flow · commit f804b0906e2c · 2021-09-15T09:18:30.000+02:00
- With setuptools&gt;=58.0.0 the installation of ibm_db package fails with `use_2to3 is invalid.`. Reason is that this feature has been removed from setuptools beginning with 58.0.0. To make the build working again setuptools is pinned to the latest version before 58.0.0.
  When the ibm_db package is upgraded to a newer version, the pin of setuptools ran be removed.
