d/changelog: version should be 1.1.0-1
d/control: you may need to specify all the deps from requirements.txt in the binary package Depends to be safe.  I know dh-python guesses those but a lot of packages still explicitly specify Depends.
d/copyright: for 'Files: *' you probably should do a 'grep -r Copyright' and list all the companies
d/*.doc-base: you may want to put 'OpenStack' as author
d/rules: can you try using the following for tests? (for reference see python-osc-lib) - thomas put the smarts into openstack-pkg-tools:
   override_dh_auto_test:
   ifeq (,$(findstring nocheck, $(DEB_BUILD_OPTIONS)))
   	pkgos-dh_auto_test
   endif
