Tests

We must have integration tests for Hub CLI:

- elaborate - assemble manifest from components and compare with reference file;
- pull - get the sources (this is currently extension, which is ok);
- deploy and undeploy - work on stubs (cat output.txt) with non-trivial components and parameters / outputs interaction, compare to reference output, compare processed templates and state file.

(Currently Hub CLI is tested as a part of a proprietary test suite for SuperHub SaaS)
