[security] Don't initialize AIDE database by default

[Major Hayden]

The AIDE database initialization consumes a lot of CPU time and I/O resources. We shouldn't initialize the database by default, but this should be configurable by the deployer. This needs to be documented in the Ansible code and within the docs.
