[bitnami/spring-cloud-data-flow] Fixes and improvements (#2945)

* Ignore .DS_Store

* Spring Cloud Data Flow chart fixes and improvements:
1) added ability to configure Hibernate dialect
2) fixed issue with locating application.yaml in kubernetes cluster
3) added JDWP support
4) removed MariaDB from database comments, because external database can be PostgreSQL as well
5) fixed some wrong properties (externalDatabase.server -> externalDatabase.dataflow)

* Added changes to values-production.yaml.

* Bumped spring-cloud-dataflow to 0.1.3 version.

* Added hibernateDialect and jdwp variables to README.md.

* Fixed "missing starting space in comment"

* Fixed "java.sql.SQLInvalidAuthorizationSpecException: Access denied for user 'dataflow'@'10.244.0.5' (using password: YES)".

* Bump version to 0.2.0.

* Added support for external RabbitMQ.

* Added externalRabbitmq config to README.
Fixed typo: rabbitmq.rabbitmq -> rabbitmq.auth.

* Fixed config location, use /opt/bitnami/**/conf.
