As the download page[1], the command name is "az", not "azure". This
replaces "azure" command with "az" command for fixing it.
In addition, "az account list-locations" is correct command line to
know available location as [2].

cloud_provider option exists in ./inventory/sample/group_vars/all/all.yml
In addition, the quick start shows to create configuration by copying
./inventory/sample. So this updates path of all.yml for fitting the above.

https://github.com/colemickens/azure-kubernetes-status is deprecated
and will be removed soon as the README.
So this updates the link to the repository for a new one.
