Update to build using charmcraft

Due to a build problem with the reactive plugin, this change falls back on overriding the steps and doing a manual build, but it also ensures the CI system builds the charm using charmcraft. Changes: - add a build-requirements.txt - modify charmcraft.yaml - modify osci.yaml -> indicate build with charmcraft - modify tox.ini -> tox -e build does charmcraft build/rename -> tox -e build-reactive does the reactive build - modify bundles to use the <charm>.charm artifact in tests. and fix deprecation warning re: prefix - tox inception to enable tox -e func-test in the CI Change-Id: Ie6e4716482a1043d4936b1343b1050fc88e54403

+#   snap is necessary on the system anyway.
