James Bardin 6b700ff1fb replace lock_table with dynamodb_table in s3 cfg
Since the DynamoDB table used by the S3 backend is no longer only used
for locks, rename it in the config to remove any confusion about it
being lock-specific.

James Bardin e7502454b4 check for nil state in s3 client Get
The S3 client can return (nil, nil) when the remote state doesn't exist.
The caused a nil pointer dereference when checking the payload.MD5
against the expected value.

This can happen if the remote state was manually removed, but the digest
entry was left in the DynamoDB table.

James Bardin 91be40a577 add detailed error message s3 checksum mismatch

the case of a mismatch state checksum.

James Bardin 0022d224e8 store and verify s3 remote state checksum
Updates to objects in S3 are only eventually consistent. If the
RemoteClient has a DynamoDB table available, use that to store a
checksum of the last written state, so the object can be verified by the
next client to call Get.

Terraform currently doesn't have any sort of user feedback around
RefreshState/Get, so we poll only for a short time before returning an
error.

James Bardin 4980fa20e7 move s3 config from client to backend
The RemoteClient needs to be configured for the named state, so move the
general config to the backend.

Rename some fields for consistency.

James Bardin 9f5cf2b105 convert S3 remote state to a backend
Move the S3 State from a legacy remote state to an official backend.

This increases test coverage, uses a set schema for configuration, and
will allow new backend features to be implemented for the S3 state, e.g.
"environments".
