I snuck this in with #2263 because thought it was simply a stylistic
clarity thing, but it actually generates a resource-replacement-forcing
diff for existing resources that don't have this set in the config.
Definitely don't want that. :P

This is an iteration on the great work done by @dalehamel in PRs #2095
and #2109.
The core team went back and forth on how to best model Spot Instance
Requests, requesting and then rejecting a separate-resource
implementation in #2109.
After more internal discussion, we landed once again on a separate
resource to model Spot Instance Requests. Out of respect for
@dalehamel's already-significant donated time, with this I'm attempting
to pick up the work to take this across the finish line.
Important architectural decisions represented here:
* Spot Instance Requests are always of type "persistent", to properly
match Terraform's declarative model.
* The spot_instance_request resource exports several attributes that
are expected to be constantly changing as the spot market changes:
spot_bid_status, spot_request_state, and instance_id. Creating
additional resource dependencies based on these attributes is not
recommended, as Terraform diffs will be continually generated to keep
up with the live changes.
* When a Spot Instance Request is deleted/canceled, an attempt is made
to terminate the last-known attached spot instance. Race conditions
dictate that this attempt cannot guarantee that the associated spot
instance is terminated immediately.
Implementation notes:
* This version of aws_spot_instance_request borrows a lot of common
code from aws_instance.
* In order to facilitate borrowing, we introduce `awsInstanceOpts`, an
internal representation of instance details that's meant to be shared
between resources. The goal here would be to refactor ASG Launch
Configurations to use the same struct.
* The new aws_spot_instance_request acc. test is passing.
* All aws_instance acc. tests remain passing.
When a user tried to create an `aws_network_interface` resource without specifying the `private_ips` or `security_groups` attributes the API call to AWS would fail with a 500 HTTP error. Length checks have been put in place for both of these attributes before they are added to the `ec2.CreateNetworkInterfaceInput` struct.
Documentation was also added for the `aws_network_interface` resource.
While cidr_block is required for static route creation, there are
apparently cases (involving some combination of VPNs, Customer Gateways,
and automatic route propogation) where the cidr_block can come back nil.
This means we cannot assume it's there in the set hash calculation.
Set Elasticache Port number to not be set by default, and require
Elasticache Port number to be specified.
Also updated acceptance tests to supply port number upon resource
declaration
