Virtual environment approach no longer supported for badfish command

[dustinblack]

Latest Badfish has some issues on using virtual python environment and venv will not be supported in the long run.

We have replaced most uses of venv in #229, but one usage remains in the bootstrap role:

JetSki/ansible-ipi-install/roles/bootstrap/vars/main.yml

Line 3 in ab0bba1

badfish_cmd: "/root/badfish/src/badfish/badfish.py -u {{ lab_ipmi_user }} -p {{ lab_ipmi_password }} -i /root/badfish/config/idrac_interfaces.yml -H mgmt-"

This var is used in the tasks here:
https://github.com/redhat-performance/JetSki/blob/ab0bba1094226119fca1f7feb4bdc3b73d6c67e9/ansible-ipi-install/roles/bootstrap/tasks/20_reprovision_nodes.yml

Per #229 (comment) from Murali, we cannot use the containerized approach that we are using elsewhere in this case because we also run this in a pipeline with Airflow where Jetski is containerized.

We need to replace the badfish venv command here with a straight standalone CLI method.
