Hi,
me again. Little status update, have successfully rewritten the library
work with the container, have couple of questions about structuring it and
configuration.

1. Haven't got much experience with writing api libraries and managing
expiring tokens. Should I need to worry about token expiring? I presume it
is not needed to make a new authentification, everytime we interact with
storage. The authentification should happen once when server is starting-up
(we create a instance) and it internally keeps it. Should I implement some
kind of mechanism that refreshes the token?

2. Does the tenant id change? From the quote below I presume that getting a
tenant I just a one time deal.

> A valid token is required to access an object store. This section
> describes how to get a valid token assuming an identity management system
> compatible with OpenStack Keystone is being used. If the username, password
> and tenant details are known, only step 3 is required.

3. From a response list of tenants (as shown in the picture below) how
should I select the "right" one? For now i'm just taking the first one.

4. Is it true that a object storage container belongs to only a single
region? Now when initiating the storage library the passed in config object
requires an region key. For my trial account it's locked to Spain2.
