Fixed KRA install problem.

Currently when installing an additional subsystem to an existing
instance the install tool always generates a new random password in
the pki_pin property which would not work with the existing NSS
database. The code has been modified to load the existing NSS
database password from the instance if the instance already exists.

The PKIInstance class has been modified to allow loading partially
created instance to help the installation.
