This fixes an issue where if the implicit config location of configuration.yml does not exist that an error is returned. This does not affect the behavior when the method was either implicit or environment.

This adds a random provider which makes usage of random operations mockable, and may allow us in the future to swap out the Cryptographical CPU random generator with dedicated hardware random generators.
This allows specifying paths to a combination of files and directories with the --config option provided none of the specified file paths reside directly inside one of the specified directory paths. The directory paths are not recursive, and load .yml and .yaml files at this time.
This moves a lot of machinery for commands into a context.Context with other struct values. This allows for PreRunE's to reliably load the configuration and avoids use of global vars.
This improves all random character generator command usages to be nearly identical and reuse a large block of code. It also improves several functions to give more options when randomly generating outputs.
