Remove Twilio SendGrid dependency as they move to paid-only subscription #557
Description
Is your feature request related to a problem? Please describe.
Currently, Switcher API uses SendGrid API to handle email-based admin account subscription. This API helped us to include a more reliable option for those who want to try Cloud Switcher without using the account integration with GitHub or Bitbucket.
As per their business model change for plan subscription, and considering that Switcher API is a 100% free to use platform without consistent revenue, we decided to remove this feature completely for email verification and account reset.
