Discussion: Cleaning up Spring property configs

[aweigold]

The current repo is very narrowly focused on a single avenue of support by Spring for configuration properties (problems manifest like the discussion here: #132).

There is some expanded documentation available here: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

Furthermore, a consumer of this library may wish to make usage of centralized configuration, such as that provided by Spring Cloud config: https://cloud.spring.io/spring-cloud-config/2.1.x/single/spring-cloud-config.html

Proposal would be to:

• Expand documentation on configuration.
• Clean up configuration properties specific for ontio and place them under a common prefix ontio.
• Ensuring all variables, where possible, have defaults in base properties, that are not provided only by profiles.
• Evaluate all usages of configuration properties and ensure that they are used in a way that allows them to be changed by Spring Cloud at runtime.

I could definitely help with this, however there would be breaking changes with existing property configurations with the proposed prefix, which should be noted.

Thanks for your help. I fully agree with your, I also think current configuration needs to be clean up. Would you mind to help me to refactor it?
