Chatwoot: Feature: Send an email to all inbox members if auto assignment is turned off for the inbox

Premise

If you have an inbox with auto assignment turned off, all members of the inbox should get a notification saying that there is a new conversation in the inbox.

@sojan-official We need to decide the content of the email.

@pranavrajs I'm taking this up and starting work on this.

We will be introducing email notification settings for each agent where they can control the emails which they want to receive.

agents can opt for email notifications on conversation creation now.
