feat(bitbucket-server): Support git over ssh

[danez]

This allows checkout of repositories from bitbucket-server when http access for git is not enabled

Changes:

• in initRepo() I moved the API calls to be done before the actual git clone, so we can read the clone urls from the API response.
• Use urls from API response or fallback to current URL generation
  • Try to use http URL from API with injected auth
  • If http not available try to use ssh url
  • Otherwise generate URL from endpoint
• Removed test does not throw as it was exactly the same as works
• Added tests for all cases and adjusted the repoMock to be able to configure the clone URLs in the mock response.

Context:

Fixes #6280

This allows to use bitbucket-server instances where https is turned of for git:

Documentation (please check one with an [x])

TBD: Still missing in self-hosted config, Want to figure out how to handle known_hosts for now. See below

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please tick one)

I have verified these changes via:

• Code inspection only, or
• Newly added unit tests, or
• Unit tests + ran on a real repository

I did run real tests with local docker version of bb version 6.0.11 and 7.8.1.

One important thing: The ssh access did NOT work out of the box, because the host verification was not stored in known_hosts. I assume this is not limited to bb-server but also happens with gitlab for example. How is that handled with gitlab? Is this up to the user to add the identification to known_hosts on the machine where renovate is running? I couldn't find anything in the docs about this. I see it was mentioned here #4022 (comment) but not sure what the outcome was.

@danez any chance you have time to address leftover comments? Looks like PR is close to merge :)

@viceice, @rarkins could you take a look?

Has this been able to be tested on both types of BBS - https URLs and ssh?

I did with a docker image of bbs version 6.0 and 7.8 locally.
As mentioned above the ssh did not work out of the box, and i had to first add the bbs instance to the ssh known_hosts file first in the container where renovate did run. But otherwise it did work.
