Add parameters for secedit values

The secedit.* parameters in centrifydc.conf are overwritten by Windows
Group Policies, causing every puppet run to overwrite the config file if
the settings differ.

Add parameters for:
 - maximumpasswordage
 - minimumpasswordage
 - lockoutduration
 - lockoutbadcount
