Install.log logs AMLDAPUSERPASSWD for unprivileged demo user in plaintext

Bug description

During installation, AM logs the "demo" user password (AMLDAPUSERPASSWD) in ~/openam/install.log in plaintext. It does this even when an external user store is configured.

How to reproduce the issue

1. Install AM (with or without an external user store)
2. Search ~/openam/install.log for AMLDAPUSERPASSWD

Expected behaviour

Using embedded user store, AMLDAPUSERPASSWD should not be logged in plaintext. When using an external user store, AMLDAPUSERPASSWD shouldn't be logged at all.

Current behaviour

AMLDAPUSERPASSWD is always logged and in plaintext

Work around

None
