2e704c69ac backend/azure: Handle Container SAS/SAT 
Ignore AuthorizationFailure caused by using a container level SAS/SAT
token when calling GetProperties during the Create() call. This is because the
GetProperties call expects an Account Level token, and the container
level token simply lacks the appropriate permissions. Supressing the
Authorization Failure is OK, because if the token is actually invalid,
this is caught elsewhere when we try to actually use the token to do
work.

e24dd5a162 backend/retry: don't trip circuit breaker if context is canceled 
When the context used for a load operation is canceled, then the result
is always an error independent of whether the file could be retrieved
from the backend. Do not false positively trip the circuit breaker in
this case.

The old behavior was problematic when trying to lock a repository. When
`Lock.checkForOtherLocks` listed multiple lock files in parallel and one
of them fails to load, then all other loads were canceled. This
cancelation was remembered by the circuit breaker, such that locking
retries would fail.

36c4475ad9 rest: improve handling of HTTP2 goaway 
The HTTP client can only retry HTTP2 requests after receiving a GOAWAY
response if it can rewind the body. As we use a custom data type,
explicitly provide an implementation of `GetBody`.

38654a3bd7 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.

98709a4372 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.

Michael Eischer
512cd6ef07 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.

Michael Eischer
a60ee9b764 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.
