fix: clean up and bring up to date the ec2 instance type matrix

The new matrix was generated in the following way:

1) scraped data from aws ec2 instance type detail and pricing pages

2) formatted data for the ironfan dsl ec2 instance flavor matrix, using
   the following conventions when translating aws documentation into
   ironfan attributes

  a) :cores = vCPU
  b) :core_size = ECU/vCPU
  c) :ram = RAM in MiB
  d) :inst_disks = instance storage number of disks
  e) :inst_disk_size = instance storage disk size
  f) :ephemeral_volumes = :inst_disks
  g) :placement_groupable, :virtualization, and :ebs_opt* were borrowed from
     a previous version of this file

Squashed commit of the following:
