Feature/sendgrid airflow

[ggsdc]

This should allow us to have sendgrid and by adding the variables into de variables file (SENDGRID_MAIL_FROM and SENDGRID_API_KEY) be able to use sendgrid to send the notification emails.

Also the backend needs to be changed in the airflow.cfg file:

[email]
email_backend = airflow.providers.sendgrid.utils.emailer.send_email

This could start from the next version.

Here is all the information.
