s3: use http client with configured timeouts for s3 IAM communication
...
The default client has no timeouts configured opening network
connections. Thus, if 169.254.169.254 is inaccessible, then the client
would wait for until the operating system gives up, which will take
several minutes.

backend/retry: do not log final error if context was canceled
...
Calls to `List(ctx, ...)` are usually stopped by canceling the context
once no further entries are required by the caller. Thus, don't log the
final error if the used context was canceled.

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.
