This reverse shell was historically used to debug CI jobs interactively.
It is not used anymore, and may be causing jobs to hang, then timeout.
There is no reason to keep it, and removing it simplifies CI jobs.
Additionally it has been reported as flagged by security scanners, so
removing it makes Mitogen easier to package/adopt.
fixes#847
(cherry picked from commit a990eb3d77)
CALLBACK_VERSION et al are documented as required in
https://docs.ansible.com/ansible/2.10/dev_guide/developing_plugins.html#callback-plugins.
The need for document_fragment is noted in
cfa8075537/lib/ansible/plugins/callback/default.py (L28-L32)Fixes#758
This addresses the following error, seen while running

Ansible has no blocking services running, or really any service that
would have an outsized benefit from multiple IO waiters. Probably we
only need 1, but let's start with 2 just in case.
The undocumented 'tmp' parameter controls whether _execute_module()
would delete anything on 2.3, so mimic that. This means
_execute_remove_stat() calls will not blow away the temp directory,
which broke the unarchive plugin.
