Revert "MySQL database cleanup for paste.o.o"

Now that we've determined how to adjust Trove configuration
parameters to override extremely short default connection timeouts
imposed by our provider, switch back to using a remote database for
the loggeit installation on paste.openstack.org.

This reverts commit 8cad8d737f3a53650159ab7c00cb8e3b4649e2fb.
