Alpine: multiple py3-waitress packages: security update to 2.1.2-r0

high Tenable Self-Hosted Container Security Plugin ID 406724

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Waitress is a Web Server Gateway Interface server for Python 2 and 3. Waitress versions 2.1.0 and 2.1.1
 may terminate early due to a thread closing a socket while the main thread is about to call select(). This
 will lead to the main thread raising an exception that is not handled and then causing the entire
 application to be killed. This issue has been fixed in Waitress 2.1.2 by no longer allowing the WSGI
 thread to close the socket. Instead, that is always delegated to the main thread. There is no work-around
 for this issue. However, users using waitress behind a reverse proxy server are less likely to have issues
 if the reverse proxy always reads the full response. (CVE-2022-31015)
