Implement python template strings + dict in ```configuration.py``` module

[blakeca00]

from string import Template

t = Template('My first name is ${fname} and my last is ${lname}')

data = {
  "fname": "Blake,
  "lname": "Roberts"
}

str1 = t.substitute(data)
print(str1)

$  My first name is Blake and my last name is Roberts

This change will greatly simplify while increasing clarity and ease of management of the UpdateConfig Class.

Consider defining 1 template for each config menu question. Example:

from string import Template

q1 = Template('${question1}')
q2 = Template('${question2}')
q3 = Template('${question3}')

data = {
  "question1": "lsdkjsdl;kf lskjfdls lskjfsljf",
  "question2": "What is your name?",
  "question3": "How do you spell it?"
}

# ask questions
print(q1.substitute(data))
