Use Proton to send emails from Grafana

To allow Grafana to send emails using Proton, you need to:

1. Create an SMTP token in Proton from settings.
2. Configure Grafana using grafana.ini:

[smtp]
enabled=true
host=smtp.protonmail.ch:587
user={{SMTP username}}
from_address={{SMTP username}}
startTLS_policy=MandatoryStartTLS
password={{SMTP token}}

Where {{SMTP username}} and {{SMTP token}} should be copied from Proton.
