What this PR does / why we need it:
For AWS Route53 support is added for the chain of credential providers.
If the provider
Secret
contains the data keyAWS_USE_CREDENTIALS_CHAIN
, no credentials need to be specified.Instead the chain of credential providers is used to search for credentials in environment variables, shared credential file, and EC2 Instance Roles.
This PR is a slightly adapted variant of the PR #143.
