ASM module: "revision_name" variable not passed through

[jtangney]

module "asm" {
  source                = "terraform-google-modules/kubernetes-engine/google//modules/asm"
  asm_version           = "1.10"
  revision_name         = "asm-110"
....
}

With the above configuration, istiod should be labelled with "istio.io/rev: asm-110". However, it is not working - istiod is labelled with the default full version string e.g. "istio.io/rev: asm-1104-14".

The revision_name parameter is correctly passed to scripts/install_asm.sh.
However, that script then does not pass it through to the downloaded ./install_asm_${ASM_VERSION} script.
The ${REVISION_NAME_COMMAND_SNIPPET} variable is never initialised.

I will open a PR
