Would be nifty to be able to resolve EC2 metadata

[hairyhenderson]

This is perhaps overkill, but it'd be useful to resolve AWS EC2 metadata:

{{ec2meta "instance-id"}}

Or even to go so far as:

{{ec2tag "Name"}}

One thing I can't figure out is how to best get the region... Maybe as simple as {{ec2region}}

Ok, we have ec2meta now (#20). It grabs from the meta-data/ URL so I need something to grab from the dynamic/ URL.

[hairyhenderson]

dynamic/ is handled by #23.

Getting the region can now be done, but it's not pretty:

$ echo '{{ (ec2dynamic "instance-identity/document" | json).region }}' | gomplate
us-east-1

It'd especially be useful to be able to parse the instance-identity document more easily like {{ec2something "region"}}... But for now it's 💤-time.

Got tags and region covered by #24. Sweet!
