Description of problem:

When using rex in pull mode, foreman_ygg_worker always use /tmp as the temporary directory for the script that will be executed.

For environments when /tmp is mounted with noexec, this is a blocker.

Currently, no configuration option is available to change this path.

Version-Release number of selected component (if applicable):

Satellite 6.12
Satellite 6.13

How reproducible:

Always, when /tmp is mounted with noexec

Steps to Reproduce:

1. Configure REX in pull mode on satellite
2. Configure a client to consume the REX queue
3. Mount /tmp on the client with "noexec"
4. Try running any job

Actual results:

~~~
1:
/bin/sh: /tmp/ygg_rex857528743: Permission denied
2:
/bin/sh: line 0: exec: /tmp/ygg_rex857528743: cannot execute: Permission denied
3:
Exit status: 126
4:
StandardError: Job execution failed
~~~

Error to execute the script, due to noexec set on /tmp. No way to modify the path

Expected results:

A way to use another directory as workdir for the worker, so jobs can run.

Additional info:

/tmp appears to be hardcoded on the foreman_ygg_worker code. See https://github.com/theforeman/foreman_ygg_worker/blob/main/src/runner.go#L62

Having a variable there would be ideal.
