Fix installing with an external CA and wait for dogtag to come up

There wasn't an exception in the "is the server already installed"
check for a two-stage CA installation.

Made the installer slightly more robust. We create a cache file of
answers so the next run won't ask all the questions again. This cache
is removed when the installation is complete. Previously nothing would work
if the installer was run more than once, this should be fixed now.
The cache is encrypted using the DM password.

The second problem is that the tomcat6 init script returns control
before the web apps are up. Add a small loop in our restart method
to wait for the 9180 port to be available.

This also adds an additional restart to ensure that nonces are disabled.
