3750 IOS Boot Options don't meet the current code checks

[jeffkala]

Environment

• Python version: 3.8
• pyntc version: 1.0.0

Expected Behavior

Install_OS works on IOS regardless of which hardware or software is on the device.

Observed Behavior

Error:

INSTALL OS failed: CommandError: Command boot system flash was not successful: Unable to determine the boot system configuration syntax.

Steps to Reproduce

1. Attempt to start a install_os, on a ios device (3750)

From the device perspective its appears to be a Cisco bug where nothing shows in show run | i boot system and show boot has different outputs than what is currently supported.

C3750-X#show run | i boot system

C3750-X#show boot

This should go hand and hand with checking if a switch is part of a stack or not
