A quick and dirty way to create a host for development purposes

Create operating system if none exist, for example CentOS 7.5
Create a domain example.com
Set up Host parameters
Set up Operating System params
Set up an interface with fake MAC address and use the example domain

We need DNS server for domain to ip address mapping
Before that, we can use DHCP (which does a number of things). DHCP can ask the ISP provider for a DNS server to use
- DHCP
- can also provide Static IP address

With dynflow actions, the disable repository tasks are run concurrently, and there are race conditions. I used the following to debug:

Seeing dynflow/foreman-task errors and strange behavior on the dev box. Using this gist to collect the errrors. Not sure what is related, but documenting everything here.

Odd Behaviors:

Tasks stuck in "planning" state

Tracebacks

Seeing this one on a fresh box while enabling and disabling RH repos
