Machine type generator

[mikesplain]

Instead of updating this manually, I've created a generator for us using the aws pricing api

kops/upup/pkg/fi/cloudup/awsup/machine_types.go

Lines 74 to 93 in cfaf0b7

	var MachineTypes []AWSMachineTypeInfo = []AWSMachineTypeInfo{
	// This is tedious, but seems simpler than trying to have some logic and then a lot of exceptions
	// t2 family
	{
	Name: "t2.nano",
	MemoryGB: 0.5,
	ECU: 3 * BurstableCreditsToECUS,
	Cores: 1,
	EphemeralDisks: nil,
	Burstable: true,
	},
	{
	Name: "t2.micro",
	MemoryGB: 1,
	ECU: 6 * BurstableCreditsToECUS,
	Cores: 1,
	EphemeralDisks: nil,
	Burstable: true,
	},

I had spot checked a few of our machine types and they're not all correct so I figured this would be a better medium term solution.

I'd like to add a quick readme and docs update.

I have a better way to do this.

Alrighty this should be set now. Less deps and faster than before too!

I have a follow-up that sets some fields that we weren't using, but that I needed to do to verify the output sanely :-)

But the fields we care about match, or our values did not match what AWS (now) documents, so lgtm - thanks @mikesplain
