s3: fix Cloudflare R2 integration tests after SDKv2 update #4989

Browse Source 
Cloudflare will normally automatically decompress files with
`Content-Encoding: gzip` when downloaded. This is not what AWS S3 does
and it breaks the integration tests.

This fudges the integration tests to upload the test file with
`Cache-Control: no-transform` on Cloudflare R2 and puts a note in the
docs about this problem.

Now run `rclone lsf r2:` to see your buckets and `rclone lsf
r2:bucket` to look within a bucket.
For R2 tokens with the "Object Read & Write" permission, you may also need to add `no_check_bucket = true` for object uploads to work correctly.

Note that Cloudflare decompresses files uploaded with
`Content-Encoding: gzip` by default which is a deviation from what AWS
does. If this is causing a problem then upload the files with
`--header-upload "Cache-Control: no-transform"`
