Update docstheme options

Update openstackdocstheme options so that "Report a bug" works.
Remove git settings for last update, the theme handles this now
by default.
Remove viewdocs and autodocs options, they are for source code but this
repo has no sourcecode.

Update minimal openstackdocstheme version so that these settings work.
