ansible-test uses hardcoded /tmp with tempfile.mkdtemp() instead of relying on env vars

[sonomac]

Summary

when executing ansible-test on a Linux system having mounted /tmp with the options noexec,nosuid, the following error appears:

FATAL: Path "/tmp/ansible-test-xxxxxx-injector/python.py" should be executable, but is not. Is the filesystem mounted with the "noexec" option?

from my point of view, the code in question should rather use os.environment.get('TMPDIR', '/tmp') instead of just /tmp with tempfile.mkdtemp():

Steps to Reproduce

execute ansible-test sanity on any Linux system having /tmp mounted with the options noexec,nosuid,nodev:

$ ansible-test sanity -vvv

Expected Results

respect the environment variable TMPDIR to point to a file-system not having the restrictions of noexec,nosuid,nodev when using ansible-test

Actual Results

$ ansible-test sanity -vvv
Configured locale: en_US.UTF-8
Creating container database.
>>> Container Database

Read 0 sanity test ignore line(s) for Ansible 2.14 from: tests/sanity/ignore-2.14.txt
Running sanity test "action-plugin-docs"
Initializing "/tmp/ansible-test-kvworxnz-injector" as the temporary directory.
FATAL: Path "/tmp/ansible-test-kvworxnz-injector/python.py" should be executable, but is not. Is the filesystem mounted with the "noexec" option?

@sonomac ansible-core 2.14 is not supported and no longer receives bug fixes. Please test against one of the supported versions of ansible-core, preferably the most recent one, to see whether the bug has been fixed.

based on the current code in the develop branch, the issue is still there with the newest Ansible Version 2.17

Not really a bug, this is by design, we set dir=/tmp which overrides TMPDIR/TEMP/TMP env vars, which tempfile uses by default.

Maybe a feature request to make this configurable?
