Script to create an admin account

[tbharathchandra]

Currently, we are creating admin accounts manually. This will be a bit tricky for non-programmers so, we need a script that creates a user and corresponding doc in user collection with required fields. Doc id will be the admin's UID which is generated by Firebase auth.

Admin's doc in user collection should be:

-     isAdmin - boolean - true
-     isGuest - boolean - false
-     pincode - number - 0
-     cart - string - (leave empty)
-     delivery - string - (leave empty)
-     name - string - (your name)
-     pNum - string - (your phone number)

This script should take Firebase keys, admin name, admin phone number, email and password as input and create the account.
