# Fact: ec2_<EC2 INSTANCE DATA>
#
# Purpose:
#   Returns info retrieved in bulk from the EC2 API. The names of these facts
#   should be self explanatory, and they are otherwise undocumented. The full
#   list of these facts is: ec2_ami_id, ec2_ami_launch_index,
#   ec2_ami_manifest_path, ec2_block_device_mapping_ami,
#   ec2_block_device_mapping_ephemeral0, ec2_block_device_mapping_root,
#   ec2_hostname, ec2_instance_id, ec2_instance_type, ec2_kernel_id,
#   ec2_local_hostname, ec2_local_ipv4, ec2_placement_availability_zone,
#   ec2_profile, ec2_public_hostname, ec2_public_ipv4,
#   ec2_public_keys_0_openssh_key, ec2_reservation_id, and ec2_security_groups.
#
# Resolution:
#   Directly queries the EC2 metadata endpoint.
#
