test(e2e): improve universal app run

[lahabana]

Motivation

It was very hard to have a complete and readable state of things in the test report because we were executing one of ssh cmds in different places.
We now keep a persistent ssh session for the whole time of the app which makes things easier to track and the output easier to consume.

Implementation information

the ssh package was completely redesigned to keep an ssh session rather than forking to execute ssh commands. This makes things easier to follow, easier to write lengthy scripts without caring about escaping things correctly for bash.
Once this was done we could start a CP or run a DP with a single cmdLine instead of a list of complex calls.

This makes the report a lot easier as it avoids a lot of noisy stuff.

Other minor changes:

• Stop doing retries inside the framework. Either we should retry because it's setup or simply in an eventually. Also stop using the retry from terratest as it's very verbose.
• ignore for dockerfiles were including things that were not necessary, this made the building of images longer.
• Once this change was done we could run into clock skews with tokens. So moved the token issuance date a few seconds in the past

• Is the PR title satisfactory? Is this part of a larger feature and should be grouped using > Changelog?
• PR description is clear and complete. It Links to relevant issue as well as docs and UI issues
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as an image registry)
• IPv6 is taken into account (.e.g: no string concatenation of host port)
• Tests (Unit test, E2E tests, manual test on universal and k8s)
  • Don't forget ci/ labels to run additional/fewer tests
• Does this contain a change that needs to be notified to users? In this case, UPGRADE.md should be updated.
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label)
