Add ability to reset password

[parruda]

I'd like to be able to reset my password.

Here's a suggestion:

$ faastruby update-account --reset-password

The above command will send me an email with a confirmation token and prompt me for this token. Once I paste it in, I will be asked for the new password and a password confirmation. The CLI will then send the request to the server with this token and the password will be changed.
If the operation was successful, the CLI will ask "Do you wish to force logout from all machines and invalidate all current API credentials?". If I respond yes, the CLI will exec "faastruby logout --all".

Then I can perform a faastruby login with my new password.
