* 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).
* Add support for the IGNORE(name) directive (#183)
IGNORE is like NO_PURGE but for a spefic record instead of the whole
zone. This is very useful for instance if you have a zone where
only some records are managed externally from dnscontrol (for instance
using kubernetes external dns system).
Adding IGNORE("foo") in the zone will make dnscontrol not trying
to manage the "foo" record (and especially not deleting it).
dnscontrol will error out if the "foo" record is both ignored and
managed in dnscontrol.
This can be seen as a generic Cloudflare's ignored label.

* Deprecate CloudFlare ignoredLabels in favor of IGNORE (#183)
Since IGNORE implements a generic `ignoredLabels` system, let
the user know CF `ignoredLabels` are deprecated.
