Allow to resize a droplet permanently (i.e. apply disk resize)
if previously it was resized temporarily (CPU and RAM only).
Fixes: #13007

Fixes failing acceptance test:

Also removes all redundant type declarations in the digitalocean package.
The second step of the `TestAccDigitalOceanDroplet_ResizeWithOutDisk` acceptance test was regularly failing. Upon investigation it was found that the second step's Terraform configuration had omitted the `user_data` parameter, thus forcing Terraform to create a new droplet resource instead of updating the current resource.
```
-/+ digitalocean_droplet.foobar
disk: "20" => "<computed>"
image: "centos-7-x64" => "centos-7-x64"
ipv4_address: "138.197.0.55" => "<computed>"
ipv4_address_private: "" => "<computed>"
ipv6_address: "" => "<computed>"
ipv6_address_private: "" => "<computed>"
locked: "false" => "<computed>"
name: "foo" => "foo"
region: "nyc3" => "nyc3"
resize_disk: "true" => "false"
size: "512mb" => "1gb"
ssh_keys.#: "1" => "1"
ssh_keys.0: "5770472" => "5770472"
status: "active" => "<computed>"
user_data: "foobar" => "" (forces new resource)
vcpus: "1" => "<computed>"
```
This fixes the acceptance test by adding the missing `user_data` parameter.
IPV6 Addresses are generally case insensitive but it is recommented to
store them as lowercase (https://tools.ietf.org/html/rfc5952#section-4.3)
When Terraform didn't store them as LowerCase, we got the following
error when using in DNS records:
```
-/+ digitalocean_record.web6
domain: "mydomain.com" => "mydomain.com"
fqdn: "web02.in.mydomain.com" => "<computed>"
name: "web02.in" => "web02.in"
port: "0" => "<computed>"
priority: "0" => "<computed>"
type: "AAAA" => "AAAA"
value: "2a03:b0c0:0003:00d0:0000:0000:0b66:6001" => "2A03:B0C0:0003:00D0:0000:0000:0B66:6001" (forces new resource)
weight: "0" => "<computed>"
```
There was no need for this to be the case. We now enforce lowercase on both state and also when responses are returned from the API
* 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
Upstream in the digitalocean API, the size slug became a size
string, breaking pearkes/digitalocean.

This fixes compatibility for changes to that library.
