WRF detailed setup procedure

[marcusgaspar]

In this Pull Request I'm detailing all the setup procedures to run and test WRF v4 using Cycle Cloud. The original setup procedure was not clear enough and there were some missing steps. I took a long time to figure out the missing steps and make it work. I'm sharing this back to the community as I believe I will be useful for everybody who wants to run a WRF v4 test on Azure using Cycle Cloud.
