SES: Support templated emails

[dominik-kovacs]

Type: Feature

Is your feature request related to a problem? Please describe.
Add support for personalized template emails

Describe the solution you'd like
Enable sending templated emails via AWS SES

Describe alternatives you've considered
Use AWS SDK directly, but it would be weird to have 2 solutions for logically similar features (templated email (AWS SDK) vs non-templated (awspring ses))
