Add ability to set peering options in aws_vpc_peering_connection. (#8310) 

This commit adds two optional blocks called "accepter" and "requester" to the
resource allowing for setting desired VPC Peering Connection options for VPCs
that participate in the VPC peering.

The following arguments are supported:
* `peer_owner_id` - (Required) The AWS account ID of the owner of the peer VPC.
* `peer_vpc_id` - (Required) The ID of the VPC with which you are creating the VPC peering connection.
* `peer_vpc_id` - (Required) The ID of the VPC with which you are creating the VPC Peering Connection.
* `vpc_id` - (Required) The ID of the requester VPC.
* `auto_accept` - (Optional) Accept the peering (you need to be the owner of both VPCs).
* `accepter` (Optional) - An optional configuration block that allows for [VPC Peering Connection]
(http://docs.aws.amazon.com/AmazonVPC/latest/PeeringGuide) options to be set for the VPC that accepts
the peering connection (a maximum of one).
* `requester` (Optional) - A optional configuration block that allows for [VPC Peering Connection]
(http://docs.aws.amazon.com/AmazonVPC/latest/PeeringGuide) options to be set for the VPC that requests
the peering connection (a maximum of one).
* `tags` - (Optional) A mapping of tags to assign to the resource.
#### Accepter and Requester Arguments
-> **Note:** When enabled, the DNS resolution feature requires that VPCs participating in the peering
must have support for the DNS hostnames enabled. This can be done using the [`enable_dns_hostnames`]
(vpc.html#enable_dns_hostnames) attribute in the [`aws_vpc`](vpc.html) resource. See [Using DNS with Your VPC]
(http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-dns.html) user guide for more information.
* `allow_remote_vpc_dns_resolution` - (Optional) Allow a local VPC to resolve public DNS hostnames to private
IP addresses when queried from instances in the peer VPC.
* `allow_classic_link_to_remote_vpc` - (Optional) Allow a local linked EC2-Classic instance to communicate
with instances in a peer VPC. This enables an outbound communication from the local ClassicLink connection
to the remote VPC.
* `allow_vpc_to_remote_classic_link` - (Optional) Allow a local VPC to communicate with a linked EC2-Classic
instance in a peer VPC. This enables an outbound communication from the local VPC to the remote ClassicLink
connection.
## Attributes Reference
The following attributes are exported:
* `id` - The ID of the VPC Peering Connections
* `accept_status` - The Status of the VPC peering connection request.
* `id` - The ID of the VPC Peering Connection.
* `accept_status` - The status of the VPC Peering Connection request.
## Notes
If you are not the owner of both VPCs, or do not enable auto_accept you will still have to accept the peering with the AWS Console, aws-cli or aws-sdk-go.
If you are not the owner of both VPCs, or do not enable the `auto_accept` attribute you will still
have to accept the VPC Peering Connection request manually using the AWS Management Console, AWS CLI,
through SDKs, etc.
## Import
VPC Peering resources can be imported using the `vpc peering id`, e.g.
