Remove http-conduit (<2.2.0) constraint

Since https://github.com/aristidb/aws/issues/206 is resolved, this
constraint is no longer necessary. However, http-conduit (>=2.2.0)
requires http-client (>=0.5.0) which introduces some breaking changes.
This commit also implements those changes depending on the version.
