Feature request: support S3 compatible services #33
Description
boto3 lets you provide a URL for endpoint so you can access one of the other many service like Backblaze, Wasabi, Cloudflare etc.
As far I have understood you do not need to provide a region name when using a custom endpoint.
Using this resources:

https://www.backblaze.com/docs/en/cloud-storage-call-the-s3-compatible-api
Or you can supply "auto":

A fork for Oracle Cloud Infrastructure uses both the endpoint and adds a single region name of OCI:
dailow@39eb770
https://docs.oracle.com/en-us/iaas/api/
Easiest implementation is probably that when a user configures a custom endpoint no default region is used.
If none is configured, none is sent.
If one is configured, it is not validated by the HASS custom component.
An alternative is to support only those services for which the allowed regions are known.
In this scenario the endpoints are hardcoded or derived from the region name. So the user configures not an endpoint but a service, eg Wasabi, and a region.
Both ideas are not mutual exclusive. If a service name is configured the endpoint will be automatically generated. But a configured endpoint will act as an override.
