Now the in-tree cloud provider is deprecated and it is recommended to
the external cloud provider for OpenStack instead.
The doc described how to upgrade from the in-tree cloud provider, but
it is better to describe how to deploy the external cloud provider from
scratch instead for current situation.
This updates the OpenStack doc for this usecase.

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.

and will be removed soon as the README.
So this updates the link to the repository for a new one.
