Dropped obsolete module templates

Module templates have little benefit because
* they are not documented anywhere,
* their structure is not suitable for our modules, hence not a
  single module is written according to the templates,
* contributers better base their own modules on existing modules
  because we have modules for most OpenStack components,
* they are outdated, e.g. normalizing is a relict of
  openstacksdk<0.99.0 and results,
* they are bloated, e.g. *_info module is doing preliminary checks
  and creating filters in separate functions which proved in other
  modules to be much better readable when inlined,
* they are hard to understand, e.g. argument_spec definition is
  a huge Jinja2 template which does nothing except for copying
  arguments from one place to another,
* they are not tested.
