the docker image built from the master can not work correctly.

1, when run with command docker run -d --name manager -p 9527:9527 -p 7750:7750 apachepulsar/pulsar-manager:latest docker container can not start, show errors: Error: format string... After add SPRING_CONFIGURATION_FILE and URL environment, container can run.

here we should add a default value for 'SPRING_CONFIGURATION_FILE' and URL.

2, can not login using pulsar/pulsar account. there is a sentence in application.properties: If user.management.enable is true, the following account and password will no longer be valid.

here we should set user.management.enable default value false for beginner.
