Removing required IamInstanceProfile field from EC2
JSON serialization of Nats.

Fixes:
1. DynamoDB client throws server-side SerializationException, because
Nat's get serialized to Strings.
2. Checks for truncation of floats where Nats are actually expected.

Closes #43.
Default timestamp formats are dependent on metadata protocol.

Fixes issue mentioned in #43 where DynamoDB creation timestamps expect
unix epochs and not ISO timestamps.
Change duplicate test.
