[FeatureRequest]: long live connection support

[chernogorsky]

Is your feature request related to a problem? Please describe.

Im working on a plugin, which requires long live connection, and experience a lot of natural disconnections:
Plugin works on SBC
Main system may and will be reset without reset/reboot SBC

It'll be good if we have some tools to check the connection status,
like is_connected method

Describe the solution you propose.

Have somethihng like

class BaseConnection:
def is_connected()->bool:
return connection->current_status

Describe alternatives you've considered

At the moment I workaround it with try except, but it mess the code
Another possible workaround - is open/close connection per every command/request, which may be resource consuming operation

Provide any additional context or information.

Ex. Photos, mockups, etc.
