Allow availability_zone to be specified when creating instances

Registered by Vipul Sabhaya on 2013-06-28

Nova supports the ability to target where VMs are spun up via the availability_zone parameter. Trove should also support a similar model so users are given more control of where Databases are created, on clouds that support availability zones.

For a nice explanation of how AZs are implemented in Nova, see: http://russellbryantnet.wordpress.com/2013/05/21/availability-zones-and-host-aggregates-in-openstack-compute-nova/

1. updated the python-troveclient to take allow an optional POST parameter for creating new instances (availability-zone)

2a. Update Trove API and TaskManager to consume the availability-zone parameter if it's there.
2b. Ensure that the API does not require the availability-zone param for creating instances

3. Update Unit Tests and Trove Integration tests.

4. Update Wiki Documentation to reflect the new parameter.
