Incompatible with Python 3.8 on macOS 10.15 #1803

Expected behavior:

Execute setup without error

Actual Behavior:

Getting an error while executing the ./streisand setup script

ERROR! Unexpected Exception, this is probably a bug: cannot pickle '_io.TextIOWrapper' object

Steps to Reproduce:

1. Choose Azure as provider
2. Type no (choose default config .streisand/site.yml)

Additional Details:

Log output from Ansible or other relevant services (link to Gist for longer output):

Target Cloud Provider: Azure

Operating System of target host: n/a

Operating System of client: macOS 10.15.6

Version of Ansible, using ansible --version : 2.8.4

Output from git rev-parse HEAD in your Streisand directory : af5eb7d

Issue:

After searching around, I found that this is an ansible issue that occurs when using python >= 3.8 on macOS and was fixed in ansible version >= 2.9.1 but this project uses a lower version (2.8.4) so the error persists.

See: ansible/ansible#63973

Is it possible to update the ansible version to >= 2.9.1?
