Implement an installer for the Dogtag certificate system.

The CA is currently not automatically installed. You have to pass in the
--ca flag to install it.

What works:
- installation
- unistallation
- cert/ra plugins can issue and retrieve server certs

What doesn't work:
- self-signed CA is still created and issues Apache and DS certs
- dogtag and python-nss not in rpm requires
- requires that CS be in the "pre" install state from pkicreate
