adds support for Konnected momentary and beep/blink switches

[heythisisnate]

Description:

This PR adds support for momentary switches and beep/blink switches in the Konnected component.

A momentary switch actuates a switch for a specified time (in milliseconds) and then reverts it back to the off state. This is commonly used with a relay module to actuate a garage door opener, or with a doorbell to send a momentary trigger to sound the doorbell.

A beep/blink switch is like a momentary switch that repeats either a specified number of times or indefinitely. This is commonly used with a a piezo buzzer to make a "beep beep" sound when a door is opened, or to make a repeating beep pattern for an alarm or audible warning. It can also be used to blink lights.
