type should be required for v2.0 service create

Updated the service name to be optional, mostly matching the cli arguments
with v3 service create.
Implemented the following changes on service create:
- if only a single positional is present, it's a <type>.
  This is not currently legal so it is considered a new case.
- if --type option is present the positional is handled as <name>;
  display deprecation message
- if --name option is present the positional is handled as <type>.
  Making --type optional is new, but back-compatible
- Made --name and --type mutually exclusive.
- only '--name <service-name> <type>' shall appear in the help output
