Module name clashes

[meyer1994]

Description:

When using this library, or any library that uses it, there are name clashes
with common names used in projects. Like utils. This is the result of a
random sys.path.insert at samtranslator/feature_toggle/feature_toggle.py.

This was not breaking before, I do not know on which version it started. This
breaks CI with unpinned versions. Or, for example, it breaks when any
dependency uses this module. For example moto:

moto > cfn-lint > aws-sam-translator

Either way, modules should not modify sys.path willy-nilly.

Steps to reproduce:

1. Create an utils.py
2. Create a main.py file that first imports something that reaches
   feature_toggle.py
3. Try importing something from your utils.py

Example

# utils.py
something = 'nice'

# main.py
from samtranslator.translator.translator import Translator
from utils import something  # ImportError

Observed result:

ImportError is thrown when trying to import things from my utils.py.

Expected result:

No ImportError.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Any
2. If using SAM CLI, sam --version:
3. AWS region: Does not matter

Add --debug flag to any SAM CLI commands you are running

Also running into this. Looks like it was introduced in #1737.
