1.1.2

1.1.2 (2017-11-01)

This is a minor update to help deal with some of the issues between stacker
and stacker_blueprints both having dependencies on troposphere. It loosens
the dependencies, allowing stacker to work with any reasonably new version
of troposphere (anything greater than 1.9.0). stacker_blueprints will
likely require newer versions of troposphere, as new types are introduced to
the blueprints, but it's unlikely we'll change the troposphere version string
for stacker, since it relies on only the most basic parts of the troposphere
API.
