Cloud based loadbalancing solution

```Status:
clb-* tools (Amazon compatible commands) postponed. HOWTO for setting up a load balancer in the cloud added. Proof of concept clb project available on launchpad at http://launchpad.net/clb. clb uploaded to ppa: https://launchpad.net/~clint-fewbar/+archive/clb. https://wiki.ubuntu.com/CloudLoadbalancingHowto

Complexity:
maverick-alpha-3: 1
ubuntu-10.10-beta: 1
ubuntu-10.10: 1

Roadmap Notes:
If we run into time constraints, fall back to a HOWTO document as deliverable.
Spec timeboxed to 1 point each for Alpha3 and Beta

jib review 20100526:
 * I'd like to cut the spec down to it's bare essential: HTTP loadbalancing frontend task/image
   * Simple storage, not configuration tool dependent
   * Access over available methods (haproxy admin tool OR ssh remote command)
   * Power user feature by replacing haproxy configuration file with user version
 * Strive for minimal complexity; 2-3
 * Suggested subcycle: alpha2 for MIR, alpha3/beta for image creation

mathiaz review 20100526L
 * it seems that we're still missing the actual use case we're trying to solve. I'd suggest to focus on describing what the end result would look like for the system administrator using the loadbalancing infrastructure: what are the different steps a sysadmin would follow to set things up (writing up a scenario for example?
 * haproxy MIR is definitely a WI for maverick.
