The package cannot be found, because it is not in any of the archives listed in your sources.list file.

I modified the steps a bit for your case to be perfectly clear and as easy as possible:

sudo su -
echo deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main >>/etc/apt/sources.list
apt-get install ubuntu-cloud-keyring 
apt-get update
apt-get install quantum-lbaas-agent
