goamz API stability

[Benoît Canet]

Hi,

I am adding the Outscale provider regions declarations in goamz/aws/aws.py
Regions variable.

It turn that a bunch of endpoint are not definied for the outscale cloud
which only implements the EC2 endpoint.

It set these field to "" to indicated they are not used.

Now I am trying to find a way to make sure that the S3 api of goamz will work
fine with this.

Is it correct to change goamz S2 new constructor to return nill, false if the
region has no S3 endpoint and *S3, true if the region has an endpoint.

It does imply that callers need to change their way of doing.

Of course I would modify the juju-core code to support this.

What are your opinions ?

Best regards

Benoît
