[New Resource]: Support for ElastiCache Reserved Nodes

[mousavian]

Description

Like EC2 and RDS, Amazon's ElastiCache also allows the purchase of reserved nodes which are used if compatible ElastiCache nodes are spun up. It'd be great if the AWS provider supported the creation of these!

Requested Resource(s) and/or Data Source(s)

Data Sources:

• aws_elasticache_reserved_cache_node_offering

Resources:

• aws_elasticache_reserved_cache_node

Potential Terraform Configuration

data "aws_elasticache_reserved_cache_node_offering" "redis_micro" {
  db_instance_class   = "cache.t1.micro"
  duration            = 31536000
  offering_type       = "No Upfront"
  product_description = "redis"
}

resource "aws_elasticache_reserved_cache_node" "example" {
  offering_id    = data.aws_rds_reserved_instance_offering.redis_micro.offering_id
  reservation_id = "optionalCustomReservationID"
  node_count     = 3
}
