backend/retry: feature flag new retry behavior

retry: reduce total number of retries
...
Retries in restic try to solve two main problems:
- retry a temporarily failed operation
- tolerate temporary network interruptions
The first problem only requires a few retries, whereas the last one benefits
primarily from spreading the requests over a longer duration.
Increasing the default multiplier and the initial interval works for
both cases. The first few retries only take a few seconds, while later
retries quickly reach the maximum interval of one minute. This ensures
that the total number of retries issued by restic will remain at around
21 retries for a 15 minute period. As the concurrency in restic is
bounded, retries drastically reduce the number of requests sent to a
backend. This helps to prevent overloading the backend.

retry: ensure that there's always at least one retry
...
Previously, if an operation failed after 15 minutes, then it would never
be retried. This means that large backend requests are more unreliable
than smaller ones.

retry: limit retries based on elapsed time not count
...
Depending on how long an operation takes to fail, the total retry
duration can currently vary between 1.5 and 15 minutes. In particular
for temporarily interrupted network connections, the former timeout is
too short. Thus always use a limit of 15 minutes.

retry: add circuit breaker to load method

If a file exhausts its retry attempts, then it is likely not accessible
the next time. Thus, immediately fail all load calls for that file to
avoid useless retries.

If client.Do returns an error, then there's no body that has to be

body, immediately drain and close the body to make sure it isn't
forgotten later on.
This change in particular adds the missing `Close()` call for the
`List()` command.

rclone: Workaround for incorrect "not found" errors while listing files

rclone returns a "not found" error if an internal error occurs while
listing a folder. Ignoring this error lets restic erroneously think that
there are no files, which can cause `prune` to wipe the whole
repository.
