Update rax root pubkey example

[#9048] convert Route53 TTL to integer before comparison

The example was showing how to use the `files` option to pass in a local file as an authorized public key for root. While this works, it's a bit sloppy, given that there's a specific option, `key_name` which will use one of your public keys on your rackspace account and add it as an authorized key for root. In our case, one of our admins didn't notice the `key_name` option because they scrolled straight to the example and saw the `files` strategy.

I propose that the example still shows `files`, but not using a root public key as an example, and instead also demonstrate the `key_name` option so that it's clear from the example how to get the initial root public key deployed.

boto/Route53 are returning TTL as a string.
The route53 module is comparing it with an integer and therfore thinks the DNS entry has always changed.

Fixes #8863

Previously, the delegate_to value was stored in the module_vars of runner,
which could lead to bleeding that value across runs and incorrect hosts
being delegated to. This patch moves the value to a local variable in
the Runner class with some related refactoring of _compute_delegate() in
Runner (since the value is no longer required to be a parameter).

This commit also makes the dest parameter optional, unless update=yes
(the default), since it is not required for queries without an update.
