Add a configurable number of retries to the EC2 credential provider

In cases where the EC2 provider is configured as the only valid provider
of credentials, intermittent failures are to be expected and can be
retried safely in order to avoid a credential error.
Docs update.
Doc fix.
Update instance_collection.rb

Added gp2 volume_type to documentation
The repl now loads aws-sdk-v1.
S3Object#copy_from now correctly accepts another S3Object as param.

Fixes #624
Updated a few tests around S3Object#copy_from/#copy_to

These specs now expect the '/bucket-name/key' instead of
'bucket-name/key' as the copy source. Not slash-prefixing
the bucket name when the user gives an explicit :bucket_name
option to copy_to/from to avoid double prefixing issues.
