Objectives:
- Facilitate the generation of valid password hashes that can be used with
the `server user --user-password` CLI command.
- Encapsulate implementation details of password hashing in
the `user` package.
Adds a new `server user hash-password` CLI command to generate the
hash from a supplied password.
Modifies the `server user set/add --user-password-hash` CLI command
to accept the password hash generated using the `hash-password`
command.
Adds `GetNewProfile(ctx, rep, username)` helper to move implementation
details to the `user` package.
Includes CLI and unit tests.
Cleans up and removes unused functions.
cli: major refactoring of how CLI commands are registered
The goal is to eliminate flags as global variables to allow for better
testing. Each command and subcommand and most sets of flags are now
their own struct with 'setup()' methods that attached the flags or
subcommand to the provided parent.
This change is 94.3% mechanical, but is fully organic and hand-made.
