Using _logger.exception for a ResourceExistsError is misleading: the operation is harmless since blobs are content-addressed (SHA1) and filename is returned correctly regardless. Switch to _logger.info to avoid false-positive ERROR noise.

Attachments on Microsoft Azure Blob Storage
===========================================
This addon allows to store the attachments (documents and assets) on `Microsoft Azure
Blob Storage <https://docs.microsoft.com/azure/storage/blobs/>`_.
Configuration
-------------
Activate Azure Blob storage:
* Create or set the system parameter with the key ``ir_attachment.location``
and the value in the form ``azure``.
Configure accesses with environment variables:
* ``AZURE_STORAGE_CONNECTION_STRING`` or
* ``AZURE_STORAGE_ACCOUNT_NAME``
* ``AZURE_STORAGE_ACCOUNT_URL``
* ``AZURE_STORAGE_ACCOUNT_KEY``
One container will be created per database using the `RUNNING_ENV` environment variable
and the name of the database. By default, `RUNNING_ENV` is set to `dev`.
The container name can be overridden with environment variable ``AZURE_STORAGE_NAME``.
The strings ``{db}`` and ``{env}`` can be used inside that variable and the values
will be replaced respectively by the database name and environment name.
The container name will also be stored in the database for each attachment,
and will be used to access the right container in the storage.
This addon must be added in the server wide addons with (``--load`` option):
``--load=web,attachment_azure``
The System Parameter ``ir_attachment.storage.force.database`` can be customized to
force storage of files in the database. See the documentation of the module
``base_attachment_object_storage``.
Limitations
-----------
* You need to call ``env['ir.attachment'].force_storage()`` after
having changed the ``ir_attachment.location`` configuration in order to
migrate the existing attachments to Azure Blob Storage.
