Import from git does not work with local BitBucket

==> Description of problem:

"Import from git" functionality with a local Bitbucket instance does not work, due to repository validation that requires to repository to be hosted on Bitbucket Cloud. [1][2]

[2] https://github.com/openshift/console/blob/release-4.10/frontend/packages/git-service/src/services/bitbucket-service.ts#L18

==> Version-Release number of selected component (if applicable):

Tested in OCP 4.10

==> How reproducible: 100%

==> Steps to Reproduce:
1. Go to: Developer View > Add+ > From Git
2. Fill the "Git Repo URL" field with the BitBucket repo URL (i.e. http://<bitbucket_url>/scm/<project>/<repository>.git)
3. Select BitBucket from the "Git type" dropdowns button

==> Actual results:
"URL is valid but cannot be reached. If this is a private repository, enter a source Secret in advanced Git options"

==> Expected results:

This functionality should work also with hosted Bitbucket

==> Additional info:

To retrieve slug information from hosted BitBucket we can query: http://<bitbucket_url>/rest/api/1.0/projects/<project>/repos/<repository>

An example:

curl -ks http://bitbucket-server-bitbucket.apps.gmeghnag.lab.cluster/rest/api/1.0/projects/test/repos/test-repo | jq
