[FEATURE]-Add some useful console commands to DeviceManager class

[ndorin]

Is your feature request related to a problem? Please describe. Some useful console commands could be added to make viewing the state of devices easier

Describe the solution you'd like Add some commands like:

• getdevcommstatus: print a list of all devices (or specific device is device key specified as parameter) that implement(s) IBasicCommunication and/or ICommunicationMonitor and print the connection properties and status. Easy way to see if devices are online and communicating.
• getdevregstatus: print a list of all devices (or specific device is device key specified as parameter) that that can be registered to the TLDM and their current status. May require creation of an interface such as IRegisterable but can likely be implmented on CrestronGenericBaseDevice
