provider/aws: add ses_smtp_password to iam_access_key

AWS gives instructions for converting AWS credentials into SES SMTP
credentials here:

https://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-convert

This implements their algorithm and yields the result as an attribute on
`iam_access_key`.

* `id` - The access key ID.
* `user` - The IAM user associated with this access key.
* `secret` - The secret access key. Note that this will be written to the state file.
* `ses_smtp_password` - The secret access key converted into an SES SMTP
password by applying [AWS's documented conversion
algorithm](https://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-convert).
* `status` - "Active" or "Inactive". Keys are initially active, but can be made
inactive by other means.
