Remove deprecated parameter on puppet dc modules

During bootstrap of a DC system, the following warning was given:
"The password_hash parameter was deprecated and will be removed"
To solve this, 'password_hash' parameter was changed to 'password'
according to instructions on the deprecation notes:
https://docs.openstack.org/releasenotes/puppet-openstacklib/
victoria.html#deprecation-notes

Test Plan:
PASS: Build & Install
PASS: DC Successful Bootstrap
PASS: DC Successful Unlock
PASS: Verified that "The password_hash parameter was deprecated and will
be removed" warning was no longer present on puppet.log
