Currently all registry implementations live in a single package, which makes it bit harder to maintain. The different registry implementations do not follow the same coding style and naming conventions, which makes the code harder to read. Breakup the registry package into smaller packages based on the registry implementation. Refactor the registry packages to follow a similar coding style and naming convention. This patch does not introduce any changes in behavior.
