Added try/except around cli utils in test_contentview because make_content_view throws CLIFactoryError on error, so it is not necessary to use info to verify if content view was really created, because in that case exception would already have been thrown.

Convert and delete some old API tests

Remove the following modules:

1. `test_computeresource`
2. `test_configtemplate`
3. `test_domain`
4. `test_environments`

The first three contained no working tests and no interesting test stubs. The
existing test stubs were for goals such as creating or deleting an entity. Given
that all four relevant entities are already tested in module
`test_multiple_paths`, there is no value to the stubs.

The fourth module contains tests for creating environments with valid and
invalid names. Port these tests to module `test_environment_v2`.

Update the API documentation to reflect these changes.
