Support Redisson config through Spring Application properties

[marcushenrique]

Would you consider to expose Redisson config through Spring Application properties? In some cases it would be better if I could override only those properties that are changing between environments passing as parameters.

+1 on this. This is actually blocking us from using this project.

At the very least, Redisson config should be able to replace placeholder ${} values via System.getProperty(...) or System.getenv(...).

Our redis host and password are different in every environemnt, and hence, we cannot configure this properly unless we can externalize. the property values via placeholders.
