Add build process improvements and fixes (#221)

* Add maximum versions for all dependencies

Add maximum supported versions for pytest-cov and cryptography
packages to ensure no build breakages in the future.

* move tests to separate Makefile target

* remove tests execution from regular image build
* add new Makefile target for tests, to execute run `make test`
* update Travis job configuration to reflect this change
