refactor: Namespace config options using dot notation

[sumitshinde-84]

This pull request introduces a comprehensive update to the configuration options in the CLI package. With this update, all options have been namespaced using dot notation, making it much easier to manage and organize them. This change results in cleaner and more readable code, which will be especially beneficial as the number of configuration options continues to grow.

All configuration options, including those related to Loki and the signer, have been updated to use the dot notation format. This change also involved updating all references to these configuration options throughout the package.

The code has been thoroughly tested to ensure that the new configuration options are properly implemented and function as expected. The tests have been included in the pull request for review.

Overall, this update will make it much easier for developers to work with and maintain the configuration options in the CLI package, leading to more efficient and streamlined development processes.

closes #15
