This was possible with test fixtures but it is also conceiably possible
with older states or corrupted states. We can also extract the type from
the key so we do that now so that StateFilter is more robust.
According to the coreos [documentation](https://coreos.com/ignition/docs/latest/configuration.html), systemd units only require the name attribute per each unit. This can also be validated with the CoreOS config validator. This change allows the `ignition_systemd_unit` resource to no longer fail if given an empty `content` and `dropin`.
Also adds a test to cover this use case.
Removal of empty nested containers from a flatmap would sometimes fail a
sanity check when removed in the wrong order. This would only fail
sometimes due to map iteration. There was also an off-by-one error in
the prefix check which could match the incorrect keys.
An absolute Manta path such as /$MANTA_USER/stor/random/path or ~~/stor/random/path will not work for the path option. /$MANTA_USER/stor/ is automatically prepended to the path.
Fixes failing acceptance test:
```
$ make testacc TEST=./builtin/providers/digitalocean TESTARGS='-run=TestAccDigitalOceanVolume_Droplet'

go generate $(go list ./... | grep -v /terraform/vendor/)

--- PASS: TestAccDigitalOceanVolume_Droplet (57.38s)

Also removes all redundant type declarations in the digitalocean package.
* provider/aws: Remove hardcoded https from the ecr repository
When the ECR resource was created, we hardcoded the repository URL to
start with https://
This was a mistake as all interaction with the repository now must
include a replace function for the https:// to "" for this to be usable
We need to note this change in the backward incompatibilities
