Many cloud services prevent duplicate key pairs with different names.
Among them are Digital Ocean, Joyent Triton and Packet. Consequently, if
tests leave dangling resources it is not enough to simply randomise the
name, the entire key material must be regenerated.
This commit adds a helper method that returns a new randomly generated
key pair, where the public key material is formatted in OpenSSH
"authorized keys" format, and the private key material is PEM encoded.
Generate bucket names and object names per test instead of once at the
top level. Should help avoid failures like this one:

* 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
