Don't echo password when registering a user

[mweibel]

I think it's common to not echo the password in a shell in case you need to enter the password. I've seen that you use IO.gets for this so probably elixir would need to have a password-prompt command ( read -s works in bash e.g., don't know how to implement this though)..

There is basically no way to get a password in Erlang. We have tried some approaches but it failed under certain circunstances, @ericmj do you remember which ones?

The issue is that the shell erlang starts by default doesn't support this. If we can find a way to start a shell that supports :io.get_password we can make it work.

I'm leaving this issue open because I really want to find a good solution for this. If anyone have any ideas on how to get :io.get_password to work please post them here.

EDIT:
:io.setopts([echo: false]) also don't work in the default shell.

If you start the erlang or elixir shell in CLI (using erl or iex), the :io.get_password()(or io:get_password()) seems to work. It does however not work within an escript (or within a mix task). Isn't it possible to start the same Shell as iex or erl? (i.e. start the new shell by default)

@josevalim Should we add your workaround or is too hacky?

[josevalim]

Up to you. I guess we can try!
