Allow execution of API commands that do not require a name.

There are some commands in the IPA API that do not require
arguments, and current implementation does not allow these
commands to be execute.

This patch adds api_command_no_name to allow the execution
of such commands, which is required, for example, to create
a vaultcontainer management module.
