Brice Figureau 7b8d608019 ROUTE53: Support Route53's ALIAS record type (#239) (#301)
* Stable comparison of metadata (#239)

Iterating over a map in Go never produces twice the same ordering.
Thus when comparing two metadata map with more than one key, the
`differ` is always finding differences.

To properly compare records metadata, we need to iterate the maps
in a deterministic way.

* Support for Route53 ALIAS record type (#239)

Route53 ALIAS doesn't behave like a regular ALIAS, and is much more
limited as its target can only be some specific AWS resources or
another record in the same zone.

According to #239, this change adds a new directive R53_ALIAS which
implements this specific alias. This record type can only be used
with the Route53 provider.

This directive usage looks like this:
```js
D("example.com", REGISTRAR, DnsProvider("ROUTE53"),
R53_ALIAS("foo1", "A", "bar") // record in same zone
R53_ALIAS("foo2", "A",
  "blahblah.elasticloadbalancing.us-west-1.amazonaws.com",
   R53_ZONE('Z368ELLRRE2KJ0')) // ELB in us-west-1

```

Unfortunately, Route53 requires indicating the hosted zone id
where the target is defined (those are listed in AWS documentation,
see the R53_ALIAS documentation for links).

Integration Tests

This is a simple framework for testing dns providers by making real requests.

There is a sequence of changes that are defined in the test file that are run against your chosen provider.

For each step, it will run the config once and expect changes. It will run it again and expect no changes. This should give us much higher confidence that providers will work in real life.

Configuration

providers.json should have an object for each provider type under test. This is identical to the json expected in creds.json for dnscontrol, except it also has a "domain" field specified for the domain to test. The domain does not even need to be registered for most providers. Note that providers.json expects environment variables to be specified with the relevant info.

Running a test

  1. Define all environment variables expected for the provider you wish to run. I setup a local .env file with the appropriate values and use zoo to run my commands.
  2. run go test -v -provider $NAME where $NAME is the name of the provider you wish to run.
