Description

I have moved ConnectionType class outside Mobile class in remote/mobile.py to avoid nesting of classes and for better readability.

Motivation and Context

The class ConnectionType is inside Mobile class, which is I felt bit confusing and hard to read. So I have moved the inner class ConnectionType out of Mobile class.
