Dependency 'Requests' Fails in Python 3.6

I am attempting to use the cyclecloud-gridengine 2.0.13 release on a RHEL 7.9 scheduler VM. The yum python3 package version for this Linux distribution is 3.6.8. I am running into errors in the jetpack deployment process with Python dependencies. You can recreate the issue by running the `install.sh` line out of the `bash 'setup cyclecloud-gridengine'` block in the [scheduler.rb](https://github.com/Azure/cyclecloud-gridengine/blob/master/specs/default/chef/site-cookbooks/gridengine/recipes/scheduler.rb) recipe. Below is the error that was encountered in chef-client.log:
```

My line 526 in scheduler.rb equates to line 488. I have added some logic higher up in the file to properly install epel-release for RHEL to fix the package install of `jemalloc`. The offending portion of the bash command is the install.sh. If you run that section at the command line you receive the same error:

Requests officially supports Python 3.7+.

```

From the [requests github](https://github.com/psf/requests), python 3.6 support was dropped in [release 2.28.0](https://github.com/psf/requests/blob/4d394574f5555a8ddcc38f707e0c9f57f55d9a3b/HISTORY.md#2280-2022-06-09). Cyclecloud-gridengine 2.0.11 did not experience this problem as at the time the release package was built, requests was on version 2.26.0. When 2.0.13 was packaged as a fix for an autoscaling issue we experienced, requests version 2.28.1 was the latest available. I think one fix is to version pin the dependency for requests to <=2.27.1. Attached is a screen capture of the 2.0.11 package contents at left and the 2.0.13 contents at right.
