Request: ActionMailer with API

[joshm1204]

Feature Request:

It seems this does not integrate with ActionMailer unless you use SMTP. It would be extremely valuable to have sendgrid officially support ActionMailer with use of the sendgrid API, instead of just the SMTP settings.

Example:
https://github.com/eddiezane/sendgrid-actionmailer

Pull requests to add this feature are welcome and will be reviewed based on priority, but Twilio SendGrid is not actively building new functionality for the library.

It seems that SMTP authentication is being deprecated by sendgrid and that api sending will required soon. It would be nice if sendgrid would provide a way to use actionmailer directly with this gem.
