Change migrates the monasca-api to use oslo-config-generator in order to always build newest configuration file. That removes the need of maintaning the file along with changes to oslo configuration. The example of the file is also included in the documentation. Also: * ported case for launching api under WSGI and allowing the argument parsing of oslo to take place Story: 2000970 Task: 4865 Story: 2000964 Task: 4106 Change-Id: I57547b0e2122e40f58db5f949773900b76214526
