Feature request: Add support for deployment_type in apigee module

[blackillzone]

Hello,

Since the provider support the deployment_type argument for Apigee environment deployments (https://github.com/hashicorp/terraform-provider-google/pull/11405), it would be a nice upcoming add for the apigee module.

In the same time, we could also add the api_proxy_type parameter.

I guess it would be something like this for the module variables:

environments = {
    apis-test = {
      display_name = "APIs test"
      description  = "APIs Test"
      deployment_type = "PROXY"
      api_proxy_type = "PROGRAMMABLE"
      envgroups    = ["test"]
    }
}

And I suppose it should be optional, with default values at null, and if null, we don't set the options in the google_apigee_environment resource.

This way, the current module should be without breaking changes.
