This PR removes the `OAuthContextSettings` class, and makes the `--oauth-url` option available on each backend that uses it, so it can be configured as part of the destination.
To assemble everything related to configuring OAuth, the code was moved to the `AuthIdOptionsHelper`, such that the usage can be shared between implementations.
This PR also adds the option to set the default OAuth url from the environment variable `DUPLICATI_OAUTH_SERVICE`.
The server can then be set in the following locations (most important last):
- Environment variable
- Server-wide advanced settings
- Backup job advanced settings (or commandline)
- Destination url
This PR moves the check from the FTP backend into shared code, so all backends will now check for read/write permissions when using the "Test" button.
For situations where write permissions are not required (like restore or verify) there is a flag on the v2 API that indicates if the connection was established, so the UI can show a message suggesting that it is possible to proceed, if the current UI operation does not require write permissions.
This fixes#2473
On some locales, odd strings would parse as valid full dates, causing relative dates to be incorrectly calculated.
This commit fixes the issues and revisits the DST aware calculations with more tests.
This PR adds a unified way of supplying timeouts to each of the backends.
It also adds an opt-in way of adding commonly used options, so parsing and usage can be standardized across multiple backends.
