Closes #11467

* Add example of marking Vault values as sensitive variables

* Update website/content/docs/templates/hcl_templates/functions/contextual/vault.mdx

On a local developer machine there is a good chance the HCP_ORG_ID and
HCP_PROJECT_ID are not set since the HCP Packer client can derive this
information using the token/secret. This change initializes the location
structure with the information obtained from the client and not the
envs.

When obtaining image metadata for a HCP Packer build, Packer core will
use mapstructure to decode the image metadata and validate that is has
all of the required data set. Before this change Packer core would fail
if there is extra metadata fields in the image metadata that Packer is
  not aware.

This change removes the restriction of erroring on unused metadata
fields. Packer should only care about the fields it knows and ignore the
rest. In the future, we will add new fields to the SDK but plugins may
begin sending that data sooner.
