Add support for `UPSERT` type of actions

[luk4s]

Current implementation of update method is DELETE and CREATE (

ruby_route_53/lib/route53/dns_record.rb

Lines 66 to 77 in f96fab5

	def update(name,type,ttl,values,comment=nil, zone_apex = nil)
	prev = self.clone
	@name = name unless name.nil?
	@type = type unless type.nil?
	@ttl = ttl unless ttl.nil?
	@values = values unless values.nil?
	@zone_apex = zone_apex unless zone_apex.nil?
	@zone.perform_actions([
	{:action => "DELETE", :record => prev},
	{:action => "CREATE", :record => self},
	],comment)
	end

).

I suggest to change it to action UPSERT, which AWS describe as update of record set (see https://docs.aws.amazon.com/Route53/latest/APIReference/API_ChangeResourceRecordSets.html)

This change optimize our workflow with DNS record sets.

Make this feature sense for you ? Do you prefer implement new method upsert instead of change current update ?

Thx

Hi @luk4s,

I think an UPSERT would work just fine in place of the DELETE and CREATE. At the time this was written UPSERT hadn't yet been added to the spec.

A word of caution however. This project still works however it is not actively maintained. As you can see the last commit was 2017, and the first commit was 9 years ago. While I'm happy to review your changes, run the test suite, and publish a new release you should exercise some caution when using the gem.
