db: Move db setup code to seperate function.

docs: updated apache/nginx configs

db: Remove comment line.

db: Set `rhodecode.is_test` in `make_pyramid_app` instead of `make_app` Based on this setting the crypto backend is selected: brypt or md5. During tests md5 is used to sppedup test execution. We have to move this setting up to the pyramid layer otherwise the test DB init will use bcrypt and the tests use md5. This will result in test users not able to login.

db: Change ordering of test env setup and db connection init. - DB init sets rhodecode.model.db.ENCRYPTION_KEY - Test env setup resets rhodecode.model.db.ENCRYPTION_KEY to None - Therefore DB init has to be done after test env setup.

db: Move initialization of test environment up to pyramid layer.

db: Move database initialization up to pyramid. We need the DB during app setup. Therefore we have to move this up to the make_pyramid_app function.

docs: added initial 4.1 release notes

configs: updated configs for VCSServer connectivty options
