[rackspace|storage] Large Object Upload Support
Add joyent API version and network support GH-1853

Adding support for listing networks in the Joyent Cloud.
:joyent_version was defined in a way that it would always
fall back to the default '~6.5'. Creating servers with
a particular network requires setting :joyent_version to '~7.0'
or greater.

[AWS|RDS] Properly rescue NotFound exceptions

The following code

now returns `nil` instead of

    Excon::Errors::NotFound: Expected(200) <=> Actual(404 Not Found)

This regressed with excon 0.22.0.
