Utilize host password security when adding users through Kimchi UI

[guirkgumbo]

Is your feature request related to a problem? Please describe. When creating users under administration -> User Management -> Add User The only password requirement via the form is that that passwords are matching.

On the host OS (centos 7) password requirements are set (i.e. minlen=8).

When creating a user as via kimchi these requirements are skipped/ignored.

I made sure that the system_auth enforced the requirements for root as well.

Describe the solution you'd like Creation of user through kimchi utilizes host OS password requirements.

Describe alternatives you've considered Make sure the passwords are strong on your own.
