Update Golang Web API, add new API Endpoints, PostgreSQL, and 2 simple emails.

Currently have GoLang code for basic web API with Token Authorization using JWT (JSON Web Token) and Redis with a test user hard coded in the code (core/authentication/[login to view URL]). Also currently have a test Python script to test the API and shows current API URLs What needs to be completed: 1. Move Redis requirement to PostGreSQL 2. Create a new API endpoint (/submit) that takes POST variables and saves them to the PostGreSQL database a. Required POST Variables: type (varchar), destination_ip (varchar), comment (text) b. Additional possible POST Variables: destination_name (varchar), category (varchar) c. Upon successful submission (required fields correct and saved to database), send email (See below: Email sending page) 3. Create a Web endpoint (/admin) that requires a login (admin user permission level) a. Default view is a list of submissions in reverse chronological order, with pagination (10 per page), sortable columns, and a search function b. Users page (/admin/users) that lists/edits/add users of the system 1. User columns: permission_level (admin or user), email, name 2. Button (per user) to randomly create a password and auto email newly created password c. Email sending page (/admin/email) 1. Editable text field for a list of email addresses to email to when an incomming submisstion is successful 2. Editable text field to edit email subject 2. Editable text area to edit email body (which includes the ability to include elements of the submission [[destination_ip]] => replaced in email by actual incoming field) 4. Ability to push to Heroku and host there (without Redis) a. When pushed auto generate the /settings/keys/ automatically (don't push existing keys in repository) 5. Create a new API endpoint (/process) that tells the system to process submissions a. Only allow users with admin user permission level to trigger the endpoint b. Upon being triggered the follwoing will happen 1. Get all unprocessed submissions 2. Process each submission by sumbitting to a 3rd party API(will give test URL) 3. Upon successful submission to 3rd party API, send a submission processed email and mark submission processed c. Update Email sending page (/admin/email) 1. Add email editing for processed email (2nd email template) 2. WIth same abilities for editing email as above (3c) PM me if you want to look at the existing code. Please put "read it all" in the subject line.
