add support for updating user with encrypted-password value

[chen23]

Is your feature request related to a problem? Please describe.

In environments where a secret/password manager is not available it would be useful to have an option to use "encrypted-password" value instead of the clear-text version. This would use a hash of the password instead of the password itself.

This can be set via tmsh when modifying a user.

Describe the solution you'd like

new option to specify encrypted-password for user passwords

Describe alternatives you've considered

Currently using a post-deploy script to set encrypted-password

@dstokesf5 - Any update on this? Seems like a basic feature that we should be supporting in DO.
