944fc857eb Fix failure to detect some legacy s3 repos
Sometimes s3 listobjects for a directory includes an entry for that
directory. The restic s3 backend doesn't expect that and returns
an error.

Symptom is:
  ReadDir: invalid key name restic/key/, removing prefix
     restic/key/ yielded empty string

I'm not sure when s3 does that; I'm unable to reproduce it myself.

But in any case, it seems correct to ignore that when it happens.

Fixes #1068

9fa4f5eb6b gs: disable resumable uploads
By default, the GCS Go packages have an internal "chunk size" of 8MB,
used for blob uploads.

Media().Do() will buffer a full 8MB from the io.Reader (or less if EOF
is reached) then write that full 8MB to the network all at once.

This behavior does not play nicely with --limit-upload, which only
limits the Reader passed to Media. While the long-term average upload
rate will be correctly limited, the actual network bandwidth will be
very spikey.

e.g., if an 8MB/s connection is limited to 1MB/s, Media().Do() will
spend 8s reading from the rate-limited reader (performing no network
requests), then 1s writing to the network at 8MB/s.

This is bad for network connections hurt by full-speed uploads,
particularly when writing 8MB will take several seconds.

Disable resumable uploads entirely by setting the chunk size to zero.
This causes the io.Reader to be passed further down the request stack,
where there is less (but still some) buffering.

My connection is around 1.5MB/s up, with nominal ~15ms ping times to
8.8.8.8.

Without this change, --limit-upload 1024 results in several seconds of
~200ms ping times (uploading), followed by several seconds of ~15ms ping
times (reading from rate-limited reader). A bandwidth monitor reports
this as several seconds of ~1.5MB/s followed by several seconds of
0.0MB/s.

With this change, --limit-upload 1024 results in ~20ms ping times and
the bandwidth monitor reports a constant ~1MB/s.

I've elected to make this change unconditional of --limit-upload because
the resumable uploads shouldn't be providing much benefit anyways, as
restic already uploads mostly small blobs and already has a retry
mechanism.

--limit-download is not affected by this problem, as Get().Download()
returns the real http.Response.Body without any internal buffering.

042adeb5d0 Refactor credentials management to support multiple mechanisms.
This PR adds the ability of chaining the credentials provider,
such that restic as a tool attempts to honor credentials from
multiple different ways.

Currently supported mechanisms are

 - static (user-provided)
 - IAM profile (only valid inside configured ec2 instances)
 - Standard AWS envs (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
 - Standard Minio envs (MINIO_ACCESS_KEY, MINIO_SECRET_KEY)
