Bug description:
Hi,
I just got an update of duplicity via snap to version 0.8.15.
Running my backup script running duplicity as follows:
```
duplicity incremental
--include-filelist backup_include.lst.txt \
--exclude-filelist backup_exclude.lst.txt \
--exclude-other-filesystems \
--exclude-device-files \
--progress \
--full-if-older-than 45D \
$HOME \
boto3+s3://<bucket-name>/<folder-name>
```
...resulted in the following error:
```
Traceback (innermost last):

endpoint_url=config.s3_endpoint_url)
AttributeError: module 'duplicity.config' has no attribute 's3_region_name'
```
*Actual behaviour*
It seems like the changes introduced via
https://gitlab.com/duplicity/duplicity/-/merge_requests/19 made the parameters
`s3-region-name` and `s3-endpoint-url` mandatory, which breaks existing AWS S3
setups.
*Expected behaviour*
These parameters should be optional.
*Duplicity version*: 0.8.15
*Python version*: 3.6
*OS distro and version*: Ubuntu 20.04
*Target filesystem*: Linux to AWS S3
Thanks for your work!
EDIT: Added duplicity command.
