Issue 66 - AWS ECR Credentials

[chelomontilla]

This PR fix issue: #66

The AWS sdk has by default many ways to configure the credentials, through environment variables, using kubernetes IRSA...
I think the best option is to use the default credential provider chain so the final user can choose how to configure credentials. This solution also has the same option as before configuring AWS environment variables.
Specifying Credentials: https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html

Environment variables VERSION_CHECKER_ECR_ACCESS_KEY_ID, VERSION_CHECKER_ECR_SECRET_ACCESS_KEY and VERSION_CHECKER_ECR_SESSION_TOKEN are no longer used. Now uses the AWS sdk default credential provider chain.

Hi @chelomontilla. Thanks for your PR.

I'm waiting for a jetstack member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
