Roxana Gherle 5521e4c504 Add --os-endpoint-type cli optional argument
User should be able to specify the endpoint type through
a CLI optional argument/ENV variable setting. We will name this new
optional argument: --os-endpoint-type (Env: OS_ENDPOINT_TYPE) and
based on the value given, the service API will use that specific
endpoint type. Possible values: public, admin, internal.
