feat: split integrations.bitbucket -> bitbucketCloud / bitbucketServer

Split `integrations.bitbucket` into `integrations.bitbucketCloud`
and `integrations.bitbucketServer`
while staying backwards compatible for now
(== `BitbucketIntegration` loads from the new configs, too, if the old is not used).
