Fix connection problems in the Broadlink integration

[felipediel]

The problem

Some users are experiencing connection problems with Broadlink devices. The root of these problems is that we are ignoring the error codes that are being sent by the device in its responses.

Let's take a practical example. We need authorization to send a command. If we send a command without being authorized we will receive an authorization error. It's simple to deal with it, we just need to re-authenticate and send the command again. But currently we are not handling this exception. So once the connection is closed for some reason, the user needs to restart Home Assistant to make the device work again.

Here is a real case. Once @AndroVet's device closes the connection, the device object breaks silently because it doesn't know it has been logged out.

Proposed change

I updated the library to propagate errors in the response as exceptions. Now we just need to deal with these exceptions in Home Assistant. These are the changes I propose:

• Create a separate class to handle authentication, availability and requests to the device.
• This class will handle any communication errors that may occur and keep availability up to date.
• Import this class in the platforms and use it as a bridge to send requests to the device.

@Danielhiversen All ready. Is there any chance of merging this update this week so I can proceed with the config entries?

@MartinHjelmare @springstan Your reviews would be appreciated.
