apply-rg.sh was for Azure command version 1("azure" command) and the
command is old and version 2("az" command) is officially used today.
apply-rg_2.sh was for the version 2. In addition, the README[1] says
we need to run apply-rg.sh for applying templates.

This renames apply-rg_2.sh to apply-rg.sh for common usages of the
version 2.

The ansible-playbook needs to ssh-login to Azure virtual machines with
ssh keypair, and users need to specify ssh_public_keys for their own
ssh public key. The change of ssh_public_keys is mandatory.
So this updates contrib/azurerm/README.md to explain that.
In addition, the path of all.yml was wrong. That also is updated with
this.

apply-rg_2.sh uses 'az group deployment' command but the command is
deprecated like the following warning message:

"This command is implicitly deprecated because command group
 'group deployment' is deprecated and will be removed in a future release.
 Use 'deployment group' instead."

This updates these deprecated commands.

FYI: The command has been deprecated since [1] on azure-cli side.

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].
