Add uuidutils to oslo.utils

Oslo team was vacillating about moving uuidutils to
oslo.utils in the past. The consensus now is that it
may be still handy and has too many references for us
to fix (change references from uuidutils to use uuid.*
package directly)

Add 'auth_password' in _SANITIZE_KEYS for strutils

Cinder volume drivers may return connection_info with'auth_password',
This is an example[1], to avoid auth_password to be logged in disk,
we should mask its value with "***".
