Create issue bug report and enhancement templates (#1584)

* Create issue bug report and enchancement templates

As a followup to #899, it would be nice to highlight this function, as
well as other useful information, when users are creating new bug
reports or requests for new features. These are copied and very lightly
edited from the templates used by pandas.

* Add header for `show_versions` in issue template

Co-authored-by: Martin Fleischmann <martin@martinfleischmann.net>

* Add templates for questions and installation issues

* Add references to GIS stack exchange

* Add suggestion to look at installation issue in issue template
