* Created a new parameter for using existing resource groups
* Implemented logic to ensure temp_ and build_ can't both be used
* Implemented logic to ensure they can only be used in correct context
* Implemented tests for this logic
* Updated where required to ensure the process works
A bug was reported to Joyent, that sometimes packer UI reports that an image was created but it wasn't actually available in Triton for use. We believe that there was a bug uploading that image to Manta but that the metadata of the image was already populated and thus packer was reporting success as it was just checking for the metadata presence
This PR changes Packer to wait for the state of the image to be `active` to make sure that it has fully uploaded and is ready for use

This change constructs partial URLs for networks and subnetworks if they
are not already partial or full URLs (i.e., they do not contain a '/' in
their name). Network and subnetwork self-links are no longer retrieved
from the API.
Previously, if a user did not provide the network or subnetwork as a
fully-qualified URL (i.e., self-link), the builder would make
compute.(sub)networks.get API calls with the provided identifier to
discover the self-link. This requires the user or service account Packer
is using to have permission to describe those network resources, which
is becoming less common as IAM is used more. Specifically, a user may
have permission to launch a VM into a network/subnetwork, but will not
have permission to call APIs to describe network resources.
This changeset will detect if the defined temporary resource group
already exists. If it does, it will not destroy it, but clean up
every resource required for building that is created by Packer
individually, both on success and failure.
Unit tests have been fixed, but more tests should be added for the new
functionalities.

I got the following output from packer:
```
packer-testing % make image

-var "triton_account=stack72_joyent" \
-var "triton_key_id=40:9d:d3:f9:0b:86:62:48:f4:2e:a5:8e:43:00:2a:9b" \
-var "triton_key_material=""" \
-var "image_version=1.0.0" \

triton output will be in this color.

I can verify from the triton cli tools that the id `7b5981c4` (from the packer output) is indeed the correct ID

This brings packer into the same version of triton-go as that in Terraform, where we rewrote the package from a library with everything in 1 place to individual packages
I was able to successfully provision a machine on triton using this new change, you can find the output in the attached gist
https://gist.github.com/stack72/a64d745459107c5a16bcb156965597ce
via
- create_options: a list of options passed to lxc-create
- start_options: a list of options passed to lxc-start
- attach_options: a list of options passed to lxc-attach
Also extended existing LXC builder BATS tests to exercise the new builder
options, and added website docs.
When running in travis, metadata requests will timeout after 5 seconds.
After 24 such timeouts, we'll hit travis' build timeout of two minutes,
and the build will fail. Lowering it to 100 gets us in a safe time
limit. We _may_ need to expose a timeout env var with this logic,
however.
