fix #775

This PR makes use of the e2e framework built by CAPI and used by several providers. This is intended to address current problems described in this issue such as code repetition or a proper collection of logs in case of failure. By adopting this framework, much of the code required for each test (such as test environment creation) is imported from the CAPI framework. On the other hand, a log dump of all relevant test components logs + configuration used is implemented if the test fails, improving the debugging capability of the test in case of failure. It also improves the ability to test against different infra providers, making use of an appropriate configuration file. In general, this approach makes e2e testing quite configurable.

The idea is as more e2e tests are added, to properly build CI using the parallelism feature (if needed in the test) and combine it with the test execution using Github Actions matrix feature. For now, a basic configuration is sufficient. The intention is to migrate the current tests little by little from the current approach to the proposed one.
