There are three "deeper" changes included with this update:
1) The `Detach` function got removed from the `StorageActionsService` in
favor of `DetachByDropletID` (which is now used in
`resource_digitalocean_volume.go`).
2) The `Update` function got removed from `TagsService` (renaming a tag
has been deprecated in the API).
3) Every function in godo now takes a `context.Context` as first
argument, so I've changed all calls to send in a `context.Background()`.
This changeset fixes how some digitalocean dns records were getting
parsed. In particular, it allows for understanding "@" as shorthand for
the domain itself, preventing terraform from suggesting changes that
wouldn't have any actual effect. This changeset also adds a trailing "."
to certain record types which are required to be submitted with a
trailing dot, but which digitalocean does not return with a trailing
dot, again preventing changes that wouldn't have an effect.
Tests have been added for the above, and with just adding the tests, the
current code is failing, as it is handling some records(e.g. MX)
incorrectly
Fixes failing acceptance test:
```
$ make testacc TEST=./builtin/providers/digitalocean TESTARGS='-run=TestAccDigitalOceanVolume_Droplet'
==> Checking that code complies with gofmt requirements...
go generate $(go list ./... | grep -v /terraform/vendor/)

```
Also removes all redundant type declarations in the digitalocean package.
* Add SSH Keys to all droplets in tests, this prevents acctests from
spamming account owner email with root password details
* Add a new helper/acctest package to be a home for random string / int
implementations used in tests.
* Insert some random details into record tests to prevent collisions
* Normalize config style in tests to hclfmt conventions
