Upgrade to RDS API version 2012-04-23

[marksidell]

Boto is currently using RDS API version 2011-04-01. Among other things, this version doesn't provide access to RDS SGs that are associated with VPCs. For example, RDSConnection().get_all_dbsecurity_groups() doesn't list them.

I also ran into this. I fixed it for myself with the following invocation:

connection = boto.connect_rds()
connection.APIVersion = '2012-09-17'

The RDS API is now at 2012-09-17 as of PR #1028
