[Feature]: allow the name of the dns record set to be configurable

[purpleclay]

Describe your feature

Support the creation of a friendly DNS name for the running EC2 instance. This should be configured by either defining an explicit value or using a Go template

Your potential solution

Specifying the root domain name is optional and will automatically be appended (along with .dns53) if missing. The DNS name will be provided through a new flag called --dns-name.

As an example, if the root domain was test:

• --dns-name my.domain => my.domain.dns53.test
• --dns-name {{ .IPv4 }}.{{ .Region }} => 172-10-1-0.eu-west-1.dns53.test

Any additional information?
