Lock Implementation for endpoints that send emails

[aditya-gitte]

Added Locks

• The locking mechanism has been carried forward from Shoonya
• Locks have been added to only the endpoints that call a celery task to send email
• All locks are stored in Redis
• This implementation is fail safe, i.e in case of any failure in this mechanism the normal functioning of neither the task nor the endpoint is hindered
